Used as a key intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. It participates in condensation reactions to form fused ring systems, which are common structural motifs in bioactive molecules. Its reactivity allows for functionalization at multiple sites, making it valuable in the development of agrochemicals, dyes, and specialty polymers. Also employed in research settings for building complex molecular architectures through cycloaddition and nucleophilic addition reactions.
