  • Applications

    2-Bromophenol (CAS 95-56-7) is primarily used as an organic synthesis intermediate, serving as a building block for brominated aryl compounds bearing a phenol group; it is employed as a precursor in the manufacture of pharmaceuticals and agrochemicals; it is also used in the production of dyes and pigments; in polymer and materials chemistry, it provides a starting point for specialty polymers and resin formulations; it may function as an odorant or fragrance chemistry intermediate in perfumery, depending on formulation and regulatory constraints.
