Description
Ethyl bromide (CAS 74-96-4), also known as bromoethane, Bromethan, 1-Bromethan, F 160B1, and NSC 8824, is a low-boiling organobromine compound classified under HS code 29033999. It carries no assigned E-code and is handled as a liquid below its boiling point in industrial settings.
In polymer and textile processing, ethyl bromide acts as a flame retardant by releasing bromine radicals during combustion, interrupting the free-radical chain reactions that sustain burning. It also functions as an alkylating agent in pharmaceutical synthesis and serves as an antimicrobial fumigant in agricultural and storage applications, where it disrupts microbial cell function at low concentrations.
Ethyl bromide is supplied in reagent and technical grades, with availability subject to REACH registration requirements within the EU. Procurement teams should confirm SDS documentation and confirm compliance with applicable national restrictions before ordering. Packaging formats typically include drums and ISO containers depending on volume.
