  • Applications

    2,4-Dibromophenol (CAS 615-58-7) is primarily used as a chemical intermediate for the synthesis of brominated phenol derivatives, including agrochemical and pharmaceutical intermediates. It also serves as a building block for specialty dyes and pigments, and as a precursor for brominated flame-retardant additives used in polymers and coatings. In industrial manufacturing, it functions as a reactive phenolic substrate for specialty polymers and electronic materials, with use governed by local regulations and formulation limits.
