1-Bromobutane

1-Bromobutane (CAS 109-65-9), also known as n-butyl bromide or butyl bromide, is a short-chain alkyl halide produced by reacting n-butanol with hydrobromic acid. It carries no E-code designation and is classified under HS code 29033036 within the organobromine compounds category.

In pharmaceutical synthesis, 1-bromobutane functions as an alkylating agent, introducing a butyl group onto nitrogen, oxygen, or sulfur nucleophiles during active pharmaceutical ingredient manufacturing. It also serves as a catalyst activator in polymer processing and contributes bromine-based flame retardancy in textile and plastics applications by releasing bromine radicals that interrupt combustion chain reactions.

This product is supplied as a reagent-grade liquid compliant with REACH registration requirements for the European market. It is available in standard laboratory and bulk industrial packaging formats. Procurement teams should confirm purity specifications and SDS documentation prior to ordering for regulated pharmaceutical or polymer applications.
