Description

1-Bromopropane (CAS 106-94-5 ), commercially known as n-propyl bromide or nPB, is a short-chain alkyl halide used primarily as an industrial solvent and chemical intermediate. It gained traction as a cleaning and degreasing solvent following restrictions on ozone-depleting alternatives, and serves as a key building block in pharmaceutical and polymer synthesis. In pharmaceutical manufacturing, nPB functions as a reaction solvent and alkylating agent for producing active pharmaceutical ingredients and specialty intermediates for various applications. Precision cleaning applications, including electronics defluxing, metal degreasing, and aerospace component cleaning, rely on its solvency for oils, greases, and flux residues. In polymer chemistry, it acts as a catalyst precursor and chain-transfer agent in controlled polymerization processes to ensure high quality and consistent chemical performance. Flame retardant formulations also incorporate 1-bromopropane as a reactive intermediate in the synthesis of brominated compounds used across several industrial manufacturing sectors. 1-Bromopropane is supplied as a clear liquid in drums, IBCs, and bulk quantities. Technical and high-purity grades are available, with purity levels typically ranging from 99% to 99.9%+. Stabilized formulations are standard for solvent-use grades to prevent degradation during storage and transport, meeting rigorous industrial and chemical manufacturing requirements.
