lead di(acetate) (CAS 301-04-2) — Safety Data Sheet

Safety data sheet documentation for lead di(acetate) (CAS 301-04-2), compiled to REACH Annex II with classification read against the harmonised entry in CLP Annex VI (H360Df, H373, H400, H410). Two options: a working draft sent by e-mail immediately, or a signed card issued within 72 hours of complete input. The item supplied is a document — MolGod.org does not sell, supply or ship chemical substances.

Free, and generated automatically from the sources listed on this page. No person has reviewed it, and it describes the substance in general — not your material, your process or your intended market.

Wat u ontvangt — en wat dit niet is

Wat u ontvangt

  • Een digitaal veiligheidsinformatieblad als PDF in de structuur met zestien rubrieken van REACH-bijlage II (Verordening 1907/2006).
  • Stofidentificatie, gevarenindeling, fysisch-chemische, toxicologische en ecologische informatie en verwijzingen naar regelgeving.
  • Indeling getoetst aan de geharmoniseerde vermelding in bijlage VI van CLP, waar die voor de stof bestaat.
  • Een versienummer, een opstellingsdatum en de bron achter elke waarde die er een heeft.
  • Levering per e-mail. Er wordt niets verzonden.

Wat dit niet is

  • Geen chemische stof, geen monster, geen enkel fysiek goed.
  • Geen certificering. In de Europese Unie bestaat geen officieel certificeringsschema voor veiligheidsinformatiebladen.
  • Geen juridische goedkeuring en geen garantie van naleving in welk rechtsgebied dan ook.
  • Geen vervanging voor uw eigen regelgevende beoordeling, noch voor het veiligheidsinformatieblad van de fabrikant of importeur van de stof die u daadwerkelijk in bezit hebt.
  • Niet afgestemd op een specifieke werkplek, een specifiek proces of een nationale bijlage, tenzij u die informatie verstrekt.

Waar het beschikbare bewijs een waarde niet onderbouwt, vermeldt het blad dat de waarde niet is vastgesteld in plaats van een schatting te geven. Een veld zonder vastgelegde bron wordt als zodanig gemarkeerd.

Wat er in het inkooppakket zit

Alles waar uw compliance officer om zal vragen, in één bestand.

  • De productpagina als pdf — het record zoals gepubliceerd, zodat wat u doorstuurt overeenkomt met wat u leest.
  • Het veiligheidsinformatieblad op uw rechtenniveau — zestien rubrieken in de volgorde die bijlage II bij REACH voorschrijft, voor deze stof, in de taal die u kiest.
  • Het CLP-etiketontwerp — gegenereerd uit dezelfde indeling als het blad, zodat de twee elkaar niet kunnen tegenspreken.
  • De specificatie, en het analysecertificaat waar batchgegevens bestaan.
  • sources.txt — elke bronvermelding met de datum waarop ze is geraadpleegd.
  • Een expliciete lijst van wat we niet konden vaststellen — velden gemarkeerd als niet beschikbaar in plaats van ingevuld met een schatting. Dit is het eerlijke deel van het document en we verstoppen het niet in een voetnoot.

Uw Europese inkoper gaat dit doorsturen naar iemand die niet bij het gesprek was. Het pakket bestaat zodat wat hij doorstuurt volledig, zelfverklarend en herleidbaar is — in plaats van vier bijlagen en een zin die begint met “Ik denk dat dit alles is”.

Hiermee wijzigt u de taal van deze pagina. Single substances. Mixtures on enquiry. One document, one language — additional languages are priced separately. Every version, including the Chinese one, is written to EU law — (EC) No 1907/2006 (REACH) Annex II and (EU) 2020/878 — and translated from it. The Chinese version is a reference translation, not a legally valid document for the Chinese market: an SDS for China must be compiled separately to GB/T 16483 and GB/T 17519.

About the downloads (Type of data: Predicted (calculated by nmrshiftdb2, not measured) — inferred: the source file carries no deposited measurement)
JCAMP: the NMRShiftDB file as received (JCAMP-DX 5.01 text). It is a peak list: chemical shift in ppm. MolGod adds header lines stating the type of data; the values are unchanged.
CSV: the same peak list in two columns. The second column repeats the shift value; it is not a signal intensity. Lines starting with # state the type of data.
PNG: a picture of the plot above, with the type of data written on it.
Use: where signals are expected or were reported (chemical shift positions). Not included or guaranteed: intensities, multiplicities, coupling constants, line shapes, and solvent or temperature unless stated. A predicted list is not a measurement and cannot serve as a reference spectrum for identity or purity testing. Downloads become active after Show.

Waarom deze pagina controleerbaar is

Identiteit

CAS, EC en molecuulformule, herleid in de identificatiesystemen die een inkoper gebruikt. Het aantal herleide systemen wordt getoond, zodat u ziet hoe goed deze stof is gekarakteriseerd in plaats van het aan te nemen.

Gegevens

Elke fysisch-chemische waarde vermeldt de bron waaruit ze afkomstig is en de datum waarop die bron is geraadpleegd. Open er gerust een.

Indeling

Getoetst aan de geharmoniseerde vermelding, waar die bestaat, met vermelding van het indexnummer. Zelfindeling wordt apart weergegeven en gemarkeerd.

Regelgeving

Status voor inventarissen, beperkingen, autorisatie en de kandidaatslijst, elk afzonderlijk vermeld. Waar een status niet is vastgesteld, zegt deze pagina dat — ze stelt nooit dat er geen beperkingen gelden.

Documentatie

Welke documenten er zijn, op welk controleniveau, in welke talen en wanneer elk ervan is uitgegeven.

Leverancier

Wie dit verkoopt en wat die over zichzelf heeft gepubliceerd.

Niets op deze pagina is een certificering. Het is een record dat u kunt auditen.

Two guarantees, both with their limits stated

The Gap Report Guarantee

If the available evidence cannot support a defensible document for your CAS number and product specification, we will not invent the missing values. You receive a documented gap report and choose: a refund, store credit, or the report on its own.

A visible gap is worth more than a plausible number, because the plausible number is the one that fails when somebody checks it.

The Re-issue Promise

If a signed card is rejected by an authority or by a customer’s compliance officer on one of the points we checked and reported as passed, we re-issue it corrected at no charge and credit the original fee.

This covers the checks we performed and named. It does not cover registration status, tonnage, or your role in the supply chain — those are not ours to hold, and a guarantee that pretended otherwise would be worth nothing.

What is the EC number for lead di(acetate)?

Alongside CAS 301-04-2, this substance carries EC number 206-104-4 and Annex VI index 082-005-00-8. European documentation is built around the EC number as often as around the CAS: registration dossiers, the candidate list and customs systems key on it. A safety data sheet quoting only one of the two forces every downstream reader to look up the other.

How is lead di(acetate) classified for road, sea and air transport?

Carriers and forwarders handling lead di(acetate) must review section 14 in relation to the shipping documents prior to loading. If there are discrepancies, the shipment should be halted at the location where rectification would incur the highest cost.

Storage and handling in the document

Section 7 of the documentation for lead di(acetate) outlines handling and storage procedures, including incompatible materials, conditions to be avoided, and any segregation requirements arising from its classification. Laboratories reviewing this section require explicit instructions rather than general warnings; for instance, a statement such as ‘store in a cool dry place’ is insufficient, as it leaves the responsibility of defining specific storage conditions to the personnel.

First-aid content and why it is read first

First-aid content for CAS 301-04-2 has to be actionable by a person who is not a chemist and is reading under pressure. Section 4 also carries notes for the attending physician, which is where the classification becomes clinically relevant.

Can I import lead di(acetate) into the EU?

An import of CAS 301-04-2 is successful or unsuccessful based on whether the accompanying document matches the register entry. Among lead compounds, a common failure arises from classification carried over from a supplier outside the Union, where the same substance may be classified differently. The binding reference is index 082-005-00-8, and discrepancies occur in restricted metal-compound consignments.

What Annex VI notes and concentration limits apply to lead di(acetate)?

The Annex VI entry for CAS 301-04-2 carries note 1. Notes are not commentary: they modify how the classification applies — to concentration ranges, to specific forms of the substance, or to the labelling that follows from it. An entry read without its notes is read incompletely.

In which language must the SDS for lead di(acetate) be supplied?

Language compliance is mandatory rather than optional. When lead di(acetate) is delivered to a customer, the receiving Member State may mandate the use of its official language, and several do so without exception. An English original that meets an auditor’s requirements in one country can be rejected at the subsequent border, with no alteration to the content but due solely to the choice of language.

Identifiers that must agree

Three identifiers accompany this substance, and all must align: the CAS number 301-04-2, the Annex VI index number 082-005-00-8, and the name as listed in the register. Incongruent identifiers represent the subtlest flaw in a documentation set, as each individual document appears correct until a cross-check reveals they describe distinct entities.

Who is responsible for REACH compliance for lead di(acetate)?

Whoever brings lead di(acetate) across the Union border carries the documentation duty, and it does not transfer back up the supply chain by contract. Section 1 has to name a contactable entity inside the Union: a foreign address there is treated as no address at all, and it is among the first things an inspector verifies because it takes seconds.

What is the CLP classification of lead di(acetate)?

The harmonised classification for CAS 301-04-2 carries 4 hazard statements: H360Df, H373, H400, H410. In plain terms this means H360Df; may cause damage to organs through prolonged or repeated exposure; very toxic to aquatic life; very toxic to aquatic life with long lasting effects. A harmonised entry is binding across the Union — an importer may not soften it, and a self-classification that diverges from it will not survive an enforcement check.

Is lead di(acetate) classified as a CMR substance?

CAS 301-04-2 is classified as a CMR substance (H360Df). That status changes the obligations attached to every shipment: workplace exposure documentation, restrictions on supply to the general public, and substitution pressure from downstream users who must justify continued use. A safety data sheet for a CMR substance is read more closely than any other, because the classification itself invites scrutiny.

Which GHS pictograms apply to lead di(acetate)?

The label for lead di(acetate) carries GHS08 (health hazard), GHS09 (environment), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 301-04-2, and the precedence rules in Annex I decide which pictogram is dropped when two would say the same thing. A label showing a different set from the register is wrong even if every hazard statement on it is correct.

Is lead di(acetate) on the SVHC candidate list?

Yes — lead di(acetate) appears on the candidate list of substances of very high concern. That triggers duties that classification alone does not: notification to ECHA above the tonnage threshold, and an obligation to inform recipients where the substance is present in an article above 0.1 % by weight.

What do customs check when importing lead di(acetate)?

When a consignment of lead di(acetate) is stopped at the border, the document examined first is rarely the invoice. It is section 14 of the safety data sheet and its agreement with the transport papers. A missing packing group, an absent UN number or a proper shipping name that contradicts the classification of CAS 301-04-2 will hold the pallet regardless of how complete the remaining fifteen sections are.

What must the label for lead di(acetate) contain?

The supply label for lead di(acetate) is generated from the same classification that drives the safety data sheet: pictograms selected by precedence, one signal word derived from the highest hazard class present, and the hazard statements H360Df, H373, H400… reproduced in full. Where the container is too small to carry the complete set at a legible size, there are lawful ways to handle it and unlawful ones that look identical to a non-specialist.

Questions about documentation for lead di(acetate)

Can I check whether my existing sheet is still valid?

Yes. A section-by-section reading against Annex II and the current harmonised entry establishes that in one pass, and a sheet that passes is reported as passing.

Do I need a safety data sheet to import lead di(acetate) into the EU?

Yes. A sheet compiled to Annex II of REACH must exist before the first consignment moves, and it must be held by the entity placing the substance on the Union market.

What is the CAS number of lead di(acetate)?

CAS 301-04-2. In CLP Annex VI the same substance carries index number 082-005-00-8, and both identifiers should appear in the documentation.

Is lead di(acetate) a CMR substance?

Yes. The harmonised classification places it among substances classified as carcinogenic, mutagenic or toxic for reproduction, which changes workplace documentation and supply restrictions.

Niets houdt u tegen om een concept naar wie dan ook te sturen. ‘Niet hiervoor geschreven’ betekent precies dat: het draagt geen handtekening en geen velden die op uw bedrijf zijn afgestemd, en beantwoordt dus niet de vragen die de ontvanger zo meteen gaat stellen.

Wat de handtekening betekent

Wie het document opstelt
The document is generated by the MolGod engine from ECHA CLP Annex VI and the cited public sources, then read section by section by a qualified scientific reviewer with a degree in chemistry or a related scientific field.
Wat de beoordeling omvat
Het blad wordt rubriek voor rubriek getoetst aan de structuur van REACH-bijlage II. De GHS-indeling en de transportgegevens worden gecontroleerd aan de hand van de in het document vermelde bronnen, en het blad wordt aangepast aan het bedrijf, de productkwaliteit en het geïdentificeerde gebruik dat u opgeeft.

FAQ — veelgestelde vragen over PXRD
What is the 2θ angle in PXRD?
2θ is the angle between the incident beam and the diffracted beam, measured in degrees. Bragg's law (nλ = 2d·sinθ) relates the diffraction angle to the d-spacing between lattice planes. For Cu Kα (λ=1.54056 Å) typical peaks lie in the 5–70° range. Each peak corresponds to a different family of hkl planes.
How does temperature affect a PXRD pattern?
As the temperature rises, thermal expansion of the lattice increases — peaks shift towards lower 2θ. Phase transitions (enantiotropy) cause step changes in the pattern. Variable-temperature PXRD (VT-PXRD) maps the phase diagram — it identifies the temperatures of polymorphic transitions. Crucial for compounds with thermolabile polymorphs.
How is a PXRD pattern calculated from a CIF file without access to ICDD?
The pymatgen library (Python) offers XRDCalculator, which simulates a PXRD pattern from a CIF structural model: from the structure to the pattern through the structure factors F(hkl). Alternatively: VESTA (GUI), Mercury (CCDC), PowderCell. Calculated patterns are accurate for the model but may differ from experimental ones (preferred orientation effects, crystallite size, strain).
What is Rietveld refinement and when is it used?
Rietveld refinement (Hugo Rietveld, 1969) is a method of fitting the whole PXRD pattern to a structural model by least squares. It makes it possible to determine lattice parameters, atomic positions and the percentage phase composition of a mixture. It is used when you need more than identification — for example to quantify polymorphs or to refine a structure from powder data.

ILLUSTRATIVE FRAGMENT ARRANGEMENT — relative positions are not structural data

No source 3-D conformer was available to MolGod for this substance. MolGod Scientific computed this geometry from the structural formula with RDKit 2026.03.6 (ETKDGv3 conformer generation, MMFF94 force-field optimisation; lowest-energy converged conformer of a fixed-seed set). It is not a measured structure, it does not come from PubChem, and it has not been compared with experimental data. It shows one possible conformation.

This substance consists of 3 separate components (for example ions). Each component was computed separately; they are arranged radially around a layout anchor for visualisation only (at least 3.0 Å apart). Their relative positions are not a crystal structure, coordination geometry, ionic contacts or any experimentally determined arrangement.
