Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its reactive alkyne and ketone functional groups allow it to participate in cyclization reactions, forming heterocyclic compounds such as indoles and pyrazoles, which are common scaffolds in bioactive molecules. Also employed in the development of novel antimicrobial and anticancer agents through derivatization. Its chlorophenyl moiety enhances lipophilicity, making it useful in modifying drug candidates for improved membrane permeability.
