Used as a key intermediate in organic synthesis, particularly in the preparation of complex aromatic and heterocyclic compounds. Its conjugated ketone and allene functionalities make it valuable in cycloaddition and coupling reactions to build pharmaceuticals and agrochemicals. It serves in the synthesis of chalcone derivatives, which exhibit biological activities such as anti-inflammatory, antimicrobial, and anticancer properties. Also employed in materials science for developing organic semiconductors and fluorescent dyes due to its extended π-conjugation system.
