Used as a key intermediate in the synthesis of benzoxazine derivatives, which serve as important precursors for bioactive pharmaceutical compounds, particularly in the areas of antimicrobials, antivirals, and central nervous system therapeutics. The bromine substituent enables facile subsequent reactions, such as nucleophilic substitution or carbon-carbon bond formation through copper- or palladium-catalyzed couplings, making it suitable for structural modifications during the development of new drugs. Its reactivity also supports the preparation of fused heterocyclic systems for broader medicinal chemistry applications.
