Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for 2,2-Bis(bromomethyl)-1,3-p…

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 2,2-Bis(bromomethyl)-1… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements

2,2-Bis(bromomethyl)-1,3-propa… precautionary statements

CLP Annex VI assigns 4 precautionary statements to 2,2-Bis(bromomethyl)-1,3-p…. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

Response

What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation

2,2-Bis(bromomethyl)-1,3-propa… name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

2,2-Bis(bromomethyl)-1,3-propa… carcinogenicity classification

IARC classification Group 2B — Possibly carcinogenic to humans
IARC monographs Volume 77: (2000) Some Industrial Chemicals

Under the conditions of these waterborne studies, 2,2-bis(bromomethyl)-1,3-propanediol at concentrations of up to 150 mg/L for 16 months was considered carcinogenic for male guppies based on increased incidences of hepatocellular adenomas or carcinomas. The study in female guppies was considered inadequate based on reduced survival. Under the conditions of these waterborne studies, 2,2-bis(bromomethyl)- 1,3-propanediol at concentrations of up to 150 mg/L for 14 months was considered carcinogenic for male medaka based on increased incidences of hepatocellular adenomas or carcinomas. The study in female medaka was considered negative.

No epidemiological data relevant to the carcinogenicity of 2,2-bis(bromomethyl)propane-1,3-diol were available. There is sufficient evidence in experimental animals for the carcinogenicity of 2,2-bis(bromomethyl)propane-1,3-diol. Overall evaluation 2,2-Bis(bromomethyl)propane-1,3-diol is possibly carcinogenic to humans (Group 2B).

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

2,2-Bis(bromomethyl)-1,3-propa… reactivity

A brominated alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
