Used as an intermediate in pharmaceutical synthesis, particularly in the development of thiophene-based drug candidates. The bromine substituent at the 4-position enables cross-coupling reactions such as Suzuki or Sonogashira couplings for further functionalization. Its protected amine group (Boc-protected) allows for selective reactions in multi-step organic syntheses. Commonly employed in the preparation of kinase inhibitors, antimicrobials, and other bioactive molecules where the thiophene ring acts as a core scaffold. Also utilized in agrochemical research for designing novel active ingredients. The tert-butyl carbamate (Boc) group ensures stability during reactions and can be easily removed under mild acidic conditions when needed.
