Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its sulfonamide group enables it to participate in reactions that form biologically active compounds. Commonly employed in the development of enzyme inhibitors and medicinal agents targeting metabolic pathways. Also utilized in buffer systems for biochemical applications due to its amphoteric nature. Shows utility in the synthesis of dyes and functional materials where nitrogen and sulfur heteroatoms contribute to electronic or structural properties.
