Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure enables incorporation into molecules with enhanced metabolic stability and binding affinity. Commonly utilized in the development of enzyme inhibitors due to the sulfonyl and amine functional groups, which facilitate strong interactions with active sites. Also applied in agrochemical research for designing novel pesticides with improved efficacy and environmental profile. The hydrochloride salt form enhances solubility and handling in aqueous reaction systems.
