Used as an intermediate in the synthesis of azo dyes and pigments with sulfonamide structures, particularly for producing colorants with good lightfastness and wash resistance in textiles and inks, suitable for cotton and synthetic fibers. Also employed in the development of pH-sensitive compounds due to its functional groups, making it suitable for analytical reagents and indicator dyes. Its structure allows for complexation with metal ions, which can be leveraged in dyeing processes requiring metal mordants. Additionally, it finds application in the production of bioactive compounds, such as antimicrobial agents during research stages, due to its versatile reactivity with biological targets.
