1-Bromopropane

1-Bromopropane (CAS 106-94-5) is a short-chain alkyl bromide solvent commercially known as n-PB and sold under trade names including Leksol, Drysolv, and Abzol JG. It carries no assigned E-code and is registered under EC number 203-445-0. The compound is classified within the halogenated solvents category.

In pharmaceutical synthesis, n-PB functions as an alkylating agent and reaction solvent, facilitating the introduction of propyl groups onto target molecules. It also serves as a flame retardant intermediate in polymer formulations, where its bromine content contributes to combustion inhibition. In biocidal applications, it acts as an antimicrobial carrier solvent in preservation systems.

1-Bromopropane is supplied in technical and synthesis grades and is subject to REACH registration requirements within the EU. Standard packaging includes drums and intermediate bulk containers. Procurement teams should verify current SVHC status and occupational exposure limits before specifying this material in formulations.
