Used as a key intermediate in organic synthesis, particularly in the preparation of natural products and bioactive compounds. Its structure allows for functionalization at multiple sites, making it valuable in constructing complex heterocyclic systems. Commonly employed in pharmaceutical research for developing compounds with potential antimicrobial, anti-inflammatory, or antioxidant activities. Also utilized in the synthesis of coumarin derivatives, which have applications in dyes, fluorescent probes, and photoreactive materials. Its reactivity supports use in cycloaddition and condensation reactions, enabling the formation of fused ring systems important in medicinal chemistry.
