Used as a key intermediate in the synthesis of biologically active indole derivatives, particularly in pharmaceuticals targeting central nervous system disorders and anticancer agents. Its bromo and sulfonyl functional groups allow for selective cross-coupling reactions, enabling the construction of complex molecular architectures in drug discovery. Commonly employed in Suzuki and Heck reactions to develop novel indole-based compounds with potential therapeutic properties. Also utilized in agrochemical research for designing new pesticides with improved efficacy and selectivity.
