This chemical is primarily used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. It plays a crucial role in the preparation of sulfonamide derivatives, which are widely employed in the creation of antibacterial and antifungal agents. Additionally, it is utilized in the synthesis of compounds with potential therapeutic applications, such as enzyme inhibitors and receptor modulators. Its reactive chlorosulfonyl group allows for further functionalization, making it valuable in constructing complex molecules for drug discovery and development.
