Used as a key intermediate in the synthesis of flavonoids and chalcone derivatives, which exhibit significant biological activities such as anti-inflammatory, antioxidant, and anticancer properties. It serves in pharmaceutical research for developing new therapeutic agents and in material science for designing organic semiconductors and fluorescent probes due to its conjugated structure and ability to undergo photoinduced electron transfer. Also employed in the preparation of nonlinear optical materials owing to its strong π-electron delocalization.
