chlorine (CAS 7782-50-5) — Safety Data Sheet

Safety data sheet documentation for chlorine (CAS 7782-50-5), compiled to REACH Annex II with classification read against the harmonised entry in CLP Annex VI (H270, H331, H335, H315). 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.

Cosa ricevi — e cosa non è

Cosa ricevi

  • Una scheda di dati di sicurezza digitale in PDF, nella struttura in sedici sezioni dell'allegato II di REACH (regolamento 1907/2006).
  • Identificazione della sostanza, classificazione dei pericoli, informazioni chimico-fisiche, tossicologiche ed ecologiche e riferimenti normativi.
  • Classificazione verificata rispetto alla voce armonizzata dell’allegato VI del CLP, ove esista per la sostanza.
  • Un numero di versione, una data di compilazione e la fonte di ogni valore che ne ha una.
  • Consegna via e-mail. Nessuna spedizione.

Cosa non è

  • Non una sostanza chimica, non un campione, né alcun bene fisico.
  • Non è una certificazione. Nell’Unione europea non esiste alcun sistema ufficiale di certificazione delle schede di dati di sicurezza.
  • Non è un’approvazione legale né una garanzia di conformità in alcuna giurisdizione.
  • Non sostituisce la tua valutazione normativa né la scheda di dati di sicurezza fornita dal fabbricante o dall’importatore della sostanza effettivamente in tuo possesso.
  • Senza adattamento a uno specifico luogo di lavoro, processo o allegato nazionale, salvo che tu fornisca tali informazioni.

Quando le evidenze disponibili non supportano un valore, la scheda indica che il valore non è stabilito anziché stimarlo. Un campo senza fonte registrata viene contrassegnato come tale.

Cosa contiene il pacchetto per l’acquirente

Tutto ciò che il tuo responsabile della conformità chiederà, in un unico file.

  • La pagina prodotto in PDF — il record così come pubblicato, affinché ciò che inoltri corrisponda a ciò che leggi.
  • La scheda di dati di sicurezza al tuo livello di accesso — sedici sezioni nell’ordine stabilito dall’allegato II del regolamento REACH, per questa sostanza, nella lingua che selezioni.
  • Il layout dell’etichetta CLP — generato dalla stessa classificazione della scheda, così i due non possono essere in contrasto.
  • La specifica, e il certificato di analisi ove esistano dati di lotto.
  • sources.txt — ogni citazione con la data in cui è stata consultata.
  • Un elenco esplicito di ciò che non siamo riusciti ad accertare — campi contrassegnati come non disponibili anziché riempiti con una stima. È la parte onesta del documento e non la nascondiamo in una nota a piè di pagina.

Il tuo acquirente europeo inoltrerà questo materiale a qualcuno che non era presente alla call. Il pacchetto esiste perché ciò che inoltra sia completo, autoesplicativo e tracciabile — anziché quattro allegati e una frase che inizia con “Credo che sia tutto”.

Questi cambiano la lingua di questa 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.

Perché questa pagina è verificabile

Identità

CAS, EC e formula molecolare, risolti nei sistemi di identificativi usati da un acquirente. Viene indicato il numero di sistemi risolti, così vedi quanto è ben caratterizzata questa sostanza invece di presumerlo.

Dati

Ogni valore chimico-fisico riporta la fonte da cui proviene e la data in cui la fonte è stata consultata. Puoi aprirne una qualsiasi.

Classificazione

Letta rispetto alla voce armonizzata, ove esista, con indicazione del numero indice. L’autoclassificazione è mostrata separatamente e contrassegnata.

Normativa

Stato negli inventari, restrizioni, autorizzazione ed elenco delle sostanze candidate, ciascuno indicato singolarmente. Dove uno stato non è accertato, questa pagina lo dice — non afferma mai che non si applicano restrizioni.

Documentazione

Quali documenti esistono, a quale livello di revisione, in quali lingue e quando ciascuno è stato rilasciato.

Fornitore

Chi lo vende e cosa ha pubblicato su di sé.

Nulla in questa pagina è una certificazione. È un record che puoi sottoporre ad audit.

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.

Documentation for chlorine, CAS 7782-50-5, prepared to the structure European enforcement expects. What is sold here is paperwork; the substance itself is not offered.

chlorine (CAS 7782-50-5) at a glance

  • Substance – chlorine
  • CAS number – 7782-50-5
  • EC number – 231-959-5
  • CLP Annex VI index number – 017-001-00-7
  • Hazard statements – H270; H331 (toxic if inhaled); H335 (may cause respiratory irritation); H315 (causes skin irritation); H319 (causes serious eye irritation); H400 (very toxic to aquatic life)
  • Hazard classes – Ox. Gas 1, Press. Gas, Acute Tox. 3 *, STOT SE 3, Skin Irrit. 2, Eye Irrit. 2
  • Label pictograms – GHS03, GHS04, GHS06, GHS09
  • Signal word – Danger
  • Annex VI notes – U
  • Concentration limits / M-factor / ATE – M = 100
  • Entry current as of – ATP01corr
  • CMR classification – not classified as CMR in the harmonised entry
  • Documentation issued – safety data sheet in REACH Annex II structure; working draft or signed card
  • What is supplied – a document. MolGod.org does not sell, supply or ship chemical substances.

Which GHS pictograms apply to chlorine?

The label for chlorine carries GHS03 (flame over circle), GHS04 (gas cylinder), GHS06 (skull and crossbones), GHS09 (environment), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 7782-50-5, 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.

What is the UN number for chlorine?

For carriage, chlorine is assigned UN 1017, transport class 2.3, with subsidiary risk 5.1+8. These entries belong in section 14 of the safety data sheet and must match the shipping papers exactly. A consignment where the sheet and the transport document disagree on the UN number is stopped before anyone reads the remaining fifteen sections.

Where is regulatory status recorded for chlorine?

The regulatory status of chlorine evolves separately from its hazard classification. A substance may maintain consistent hazard characteristics over extended periods while gaining additional obligations under Section 15, leading to this section becoming outdated more rapidly than Section 2.

What do customs check when importing chlorine?

When a consignment of chlorine 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 7782-50-5 will hold the pallet regardless of how complete the remaining fifteen sections are.

What is the CLP classification of chlorine?

The harmonised classification for CAS 7782-50-5 carries 6 hazard statements: H270, H331, H335, H315, H319, H400. In plain terms this means H270; toxic if inhaled; may cause respiratory irritation; causes skin irritation. 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.

Can I import chlorine into the EU?

An import of CAS 7782-50-5 succeeds or fails on whether the accompanying sheet matches the register. Among substances listed in CLP Annex VI the recurring failure is a classification carried over from a supplier outside the Union, where the same substance may be classified differently. Index 017-001-00-7 is the binding reference, and it is in regulated consignments that the discrepancy surfaces.

What Annex VI notes and concentration limits apply to chlorine?

The Annex VI entry for CAS 7782-50-5 carries note U. 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. The register also records M = 100 for this entry. Specific concentration limits, M-factors and acute toxicity estimates override the generic cut-off values, so a mixture calculation that ignores them will classify the mixture wrongly in both directions.

How is chlorine classified for road, sea and air transport?

The transport classification for chlorine falls under section 14 and varies depending on the mode of transport: ADR for road, IMDG for sea, and IATA for air. A document that prints all three classifications without specifying which one applies places the responsibility on the shipper to select the correct one, and it is the shipper who faces penalties for making an incorrect choice.

Documentation demand on the EU market

CAS 7782-50-5 has a recorded presence on the European trading market, which means documentation for it is requested routinely rather than exceptionally. Substances that move in commerce attract repeat scrutiny: the same sheet is read by successive customers, carriers and authorities, and a defect that survives the first reading rarely survives the tenth.

What must the label for chlorine contain?

The supply label for chlorine 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 H270, H331, H335… 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.

What concentration limits apply to chlorine?

M-factor on record: 100. The M-factor multiplies the contribution of this substance in the aquatic hazard calculation for a mixture, which is where it is most often overlooked.

What is the EC number for chlorine?

Alongside CAS 7782-50-5, this substance carries EC number 231-959-5 and Annex VI index 017-001-00-7. 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.

Identifiers that must agree

CAS 7782-50-5 and index number 017-001-00-7 are not interchangeable and not decorative. The index number ties the entry to the harmonised classification; the CAS number ties it to the chemical literature. A file carrying one without the other forces every reader to reconstruct the link, and reconstruction is where errors enter.

Which SDS sections decide whether a shipment clears?

The sixteen sections outlined in Annex II are not merely a formatting requirement; each section has a specific purpose, and inspectors review them by number. For the CAS registry number 7782-50-5, the sections typically determining acceptance are 2 (classification against the harmonised entry), 3 (composition and identifiers), 14 (transport) and 15 (regulatory status). It is imperative not to merge, renumber or omit any sections, as placeholders must remain unchanged.

Purity, certificates and what the sheet does not say

Purity grade is a certificate question, not a safety data sheet question. The sheet for chlorine describes the substance; a certificate of analysis describes one batch of it, with the measured result against the specification and the analytical method named per parameter. Laboratories asking for ‘the COA’ usually need both documents.

Questions about documentation for chlorine

What is the CAS number of chlorine?

CAS 7782-50-5. In CLP Annex VI the same substance carries index number 017-001-00-7, and both identifiers should appear in the documentation.

What hazard statements apply to CAS 7782-50-5?

The harmonised entry lists H270, H331, H335, H315. These are binding across the Union and may not be softened by a self-classification.

In which language must the sheet be supplied?

In an official language of each Member State where chlorine is placed on the market, unless that State has stated otherwise.

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.

Cosa significa la firma

Chi prepara il documento
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.
Cosa comprende la revisione
La scheda viene esaminata sezione per sezione rispetto alla struttura dell'allegato II del REACH. La classificazione GHS e le voci relative al trasporto vengono verificate rispetto alle fonti citate nel documento, e la scheda viene adattata all'azienda, al grado del prodotto e all'uso identificato che indichi.
Cosa NON viene verificato
Non analizziamo il tuo materiale e non possiamo confermare cosa si trovi fisicamente nel tuo contenitore: composizione, concentrazione, impurezze o via di produzione. Questi dati provengono da te e vengono riportati così come forniti.
Che cos'è la firma — e cosa non è
The signature records that a qualified scientific reviewer read the document. It is not a government approval, not an ECHA approval, and not a legal certification — no such certification exists for safety data sheets in the EU. A signature does not by itself make a document legally valid or make your business compliant.

FAQ — domande frequenti su PXRD
What is the COD (Crystallography Open Database)?
COD is a free database of open crystal structures (crystallography.net/cod) with more than 533,000 entries. Every structure has a CIF file (Crystallographic Information File) with complete data: cell parameters, space group, atomic coordinates, publication DOI. The data is available under a CC0 licence (public domain).
What does I/I₀ (relative intensity) mean?
I/I₀ is the intensity of a peak expressed as a percentage of the intensity of the strongest peak (I₀=100). Intensity depends on the number of atoms in the plane, their type (atomic factor) and thermal scattering. For identifying a polymorphic form it is the SET of peaks that matters — not individual values.
What is the R-factor in crystallography?
The R-factor (residual factor) measures the agreement of a structural model with experimental data: R = Σ|Fo-Fc|/ΣFo. The lower it is, the better the quality of the structure. Values < 0.05 = high quality (the five per cent rule). Values > 0.10 suggest problems with the model or with the data. The R-factor is a standard quality criterion in the CSD and COD databases.
How does SCXRD differ from PXRD?
SCXRD (Single Crystal XRD) uses a single crystal and gives full three-dimensional structural data (atomic coordinates, bond lengths). PXRD uses a powder and gives a diffraction pattern. SCXRD is more accurate, but requires a good crystal. PXRD is faster, cheaper, and is used for phase identification, analysis of mixtures and quality control.
