1-bromopropane

1-Bromopropane (CAS 106-94-5), also known as n-propyl bromide or nPB, is a short-chain alkyl halide used mainly as an industrial solvent and chemical intermediate.

Where is 1-bromopropane used?

• Pharmaceutical manufacturing: reaction solvent and alkylating agent for active pharmaceutical ingredients and specialty intermediates
• Precision cleaning: electronics defluxing, metal degreasing and aerospace component cleaning, dissolving oils, greases and flux residues
• Polymer chemistry: catalyst precursor and chain-transfer agent in controlled polymerization
• Flame retardants: reactive intermediate in synthesis of brominated compounds
• It gained traction as a cleaning and degreasing solvent after restrictions on ozone-depleting alternatives.

Commercial specifications

• Purity typically 99% to 99.9%+
• Technical and high-purity grades
• Stabilized formulations standard for solvent-use grades to prevent degradation during storage and transport
• Clear liquid in drums, IBCs and bulk quantities
