Allyl bromide

Allyl bromide (CAS 106-95-6, EC 203-446-6, formula C3H5Br) is an organobromine compound also known as 3-bromopropene or 3-bromopropylene, with the reference code NSC 7596. It carries no assigned E-code. It is classified as a pharmaceutical intermediate and handled under strict hazard protocols due to its reactivity.

In pharmaceutical synthesis, allyl bromide functions as an alkylating agent, introducing the allyl group into target molecules through nucleophilic substitution reactions. This mechanism underpins its role in producing antimicrobial active pharmaceutical ingredients and in biotechnology research where selective carbon-carbon bond formation is required at laboratory and pilot scale.

Allyl bromide is supplied in reagent and technical grades as a liquid, compliant with REACH registration requirements for the European market. Packaging typically follows hazardous liquid standards, with options ranging from small glass bottles to larger UN-approved containers. Buyers should confirm purity specifications and SDS documentation prior to procurement.
