1-bromo-3-chloropropane

1-Bromo-3-chloropropane (CAS 109-70-6), also known as trimethylene chlorobromide, is a bifunctional alkyl halide used as a chemical intermediate and flame retardant precursor in industrial manufacturing. Its dual halogen functionality makes it a reactive building block for synthesizing specialty compounds across multiple sectors. In plastics and polymer manufacturing, it serves as an intermediate in producing flame retardant additives.

These additives are incorporated into construction materials such as insulation panels and cable sheathing. The textile and leather industries use it in the synthesis of biocidal and preservative agents applied during processing. It also functions as a crosslinking and chain-extension intermediate in polymer chemistry, enabling controlled modification of material properties for construction-grade applications. This versatility is key for industrial producers.

Specialty chemical producers use it to prepare quaternary ammonium compounds and other antimicrobial actives. These are used in paper treatment and industrial preservation formulations to ensure product longevity and safety. 1-Bromo-3-chloropropane is supplied as a liquid in standard industrial drum and IBC packaging. Technical grade is the primary commercial specification available from bulk chemical suppliers for large-scale use.

Purity levels typically range from 97% to 99%+, with high-purity offerings suited to synthesis applications. This ensures that halide impurities do not affect downstream reaction yields or final product quality.
