Used primarily in the synthesis of dyes and pigments, particularly in the production of azo dyes, which are widely applied in textiles, plastics, and inks. It serves as an intermediate in the manufacture of pharmaceuticals, especially in the development of compounds targeting neurological and cardiovascular conditions. Additionally, it finds application in organic synthesis for creating complex molecules in research and industrial settings. Its role in polymer chemistry is also notable, where it is utilized to modify polymer properties for specific industrial uses.
