Used primarily in the pharmaceutical industry as an intermediate in the synthesis of various sulfonamide-based drugs. It plays a key role in the development of antimicrobial and antibacterial agents, particularly in the production of compounds targeting bacterial infections. Additionally, it is utilized in research settings for studying the structure-activity relationships of sulfonamide derivatives to enhance their efficacy and reduce side effects. Its application extends to the development of dyes and organic compounds in chemical manufacturing processes.
