What is the EC number for 1-bromopropane?

Alongside CAS 106-94-5, this substance carries EC number 203-445-0 and Annex VI index 602-[CAS?]. 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.

Is 1-bromopropane classified as a CMR substance?

CAS 106-94-5 is classified as a CMR substance (H360FD). 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 1-bromopropane?

The label for 1-bromopropane carries GHS02 (flame), GHS07 (exclamation mark), GHS08 (health hazard), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 106-94-5, 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.

Storage and handling in the document

Section 7 of the documentation for 1-bromopropane 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.

Can I import 1-bromopropane into the EU?

Bringing 1-bromopropane into the Union is a documentation exercise before it is a logistics one. The file has to exist at the moment of import, not at the moment somebody asks for it, and for substances listed in CLP Annex VI it is examined in the context of regulated consignments. Index 602-[CAS?] fixes the classification that section 2 must reproduce.

Which SDS sections decide whether a shipment clears?

A sheet for CAS 106-94-5 is read by number, not as a narrative. Subsections matter as much as sections: an inspector looking for 3.1 will not accept the information folded into a paragraph elsewhere, however complete that paragraph is. Completeness is judged by structure first and content second.

What is the CLP classification of 1-bromopropane?

The harmonised classification for CAS 106-94-5 carries 7 hazard statements: H225, H360FD, H335, H336, H373, H315, H319. In plain terms this means highly flammable liquid and vapour; may damage fertility and the unborn child; may cause respiratory irritation; may cause drowsiness or dizziness. 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.

Identifiers that must agree

Three identifiers travel with this substance and all three have to agree: CAS 106-94-5, the Annex VI index number 602-[CAS?], and the name as it appears in the register. Mismatched identifiers are the quietest defect in a documentation set, because every individual document looks correct and only a cross-check reveals that they describe different things.

Protective equipment and exposure controls

Section 8 states exposure controls and personal protection for 1-bromopropane: glove material, eye protection, respiratory protection where the classification calls for it, and any occupational exposure limit that has been set. Glove material matters more than glove presence — a nitrile glove is not universally correct.

Documentation demand on the EU market

CAS 106-94-5 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.

Accidental release and containment

Emergency procedures for 1-bromopropane are read at the moment of the incident, so section 6 is written for speed: what to evacuate, what to contain with, and what must not be used.

How is 1-bromopropane classified for road, sea and air transport?

The transport classification for 1-bromopropane 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.

Stability, reactivity and incompatibilities

The reactivity information for CAS 106-94-5 provided under Section 10 must be sufficiently detailed and actionable. While stating ‘avoid strong oxidizing agents’ offers a general category, specifying the exact chemical classes that react with the substance in question provides clearer guidance on appropriate handling and precautionary measures.

Is 1-bromopropane on the SVHC candidate list?

Yes — 1-bromopropane 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. It is also listed in Annex XIV, with a sunset date of 2020-07-04. Once a substance reaches Annex XIV, continued use in the Union requires an authorisation granted for a named use — a supplier relationship alone is not a legal basis.

Disposal route and waste classification

Section 13 for CAS 106-94-5 states the disposal route and any contaminated-packaging handling. Laboratories are audited on whether their waste stream matches what the sheet declares, so a vague section here becomes a finding on the laboratory rather than on the supplier.

Why a correct sheet stops being correct

Classification under CLP moves with each Adaptation to Technical Progress. A sheet for CAS 106-94-5 written before the amendment that touched its entry keeps stating a classification the register no longer holds. Nothing in the document announces this — it reads exactly as it did on the day it was issued, which is precisely why revision dates are checked before content.

Purity, certificates and what the sheet does not say

For CAS 106-94-5, the differentiation between grades such as technical, reagent, and analytical is documented in the certificate of analysis and the relevant specifications rather than on the safety data sheet. This confusion between the two is the most frequent documentation error observed in laboratory procurement processes.

What must the label for 1-bromopropane contain?

The supply label for 1-bromopropane 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 H225, H360FD, 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.

Questions about documentation for 1-bromopropane

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 1-bromopropane 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 1-bromopropane?

CAS 106-94-5. In CLP Annex VI the same substance carries index number 602-[CAS?], and both identifiers should appear in the documentation.

Is 1-bromopropane 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.
