  • Applications

    Bromochloromethane (CAS 74-97-5) is an industrial solvent and a precursor for the production of halogenated organics; it is used as a solvent for organic synthesis and formulation in various industrial applications. It is also employed as a cleaning and degreasing solvent in metalworking, electronics, and coatings; as a processing solvent or precursor in the polymer/plastics sector; and as an analytical extraction solvent in laboratory analysis. The use is subject to local regulations and formulation limits.
