Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes for textiles and inks. It also serves as a building block in pharmaceuticals, especially in the development of sulfonamide-based drugs with antimicrobial or anti-inflammatory properties. Its structure supports conjugation in organic semiconductors, making it useful in some electronic materials research. Additionally, it finds use in agrochemicals for modifying solubility and stability of active ingredients.
