Used as an intermediate in the synthesis of pharmaceuticals and bioactive compounds, particularly in the development of anticoagulants and anti-inflammatory agents. Its structure serves as a key building block in the preparation of coumarin derivatives, which exhibit a range of biological activities including antimicrobial, anticancer, and antioxidant properties. Commonly employed in organic synthesis for bromine-directed functionalization reactions, enabling the formation of complex heterocyclic systems. Also utilized in research settings to study reaction mechanisms involving electrophilic aromatic substitution and palladium-catalyzed cross-coupling reactions.
