Used as an intermediate in the synthesis of various pharmaceuticals, particularly in the production of anti-inflammatory and analgesic drugs. It plays a key role in creating active pharmaceutical ingredients (APIs) that target pain and inflammation management. Additionally, it is employed in the development of dyes and pigments, contributing to the coloration of textiles and materials. Its chlorosulfonyl group makes it valuable in organic synthesis, enabling the introduction of sulfonamide functionalities in complex molecules. This chemical is also utilized in research and development for designing novel compounds with potential therapeutic applications.
