  • Applications

    Bromochlorodifluoromethane (CAS 353-59-3) has historically served as a fire-suppressant clean agent in Halon-type fire protection systems, including aerospace, marine, and industrial applications, though use is now heavily restricted by regulation. It also functions as an intermediate in the manufacture of fluorinated organic compounds and may act as a solvent or processing aid in specialized fluorinated-chemistry workflows. In the past it has been employed as a blowing agent for polymer foams. In research and development, it may be evaluated as a reagent for halogenation steps or as a source of halogens in synthetic routes, subject to local regulations and formulation limits.
