Used as a key intermediate in the synthesis of flavonoid-based pharmaceuticals, particularly in the development of anti-inflammatory and anticancer agents. Its aldehyde and chloro functional groups allow for selective modifications, enabling the construction of complex heterocyclic systems. Commonly employed in condensation reactions to form chalcone derivatives and in cyclization processes to generate fused chromone structures with enhanced biological activity. Also applied in medicinal chemistry research for screening new bioactive molecules targeting kinase inhibition and antioxidant pathways.
