Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of pyrazole-based active ingredients. Its reactive chloromethyl group allows for easy functionalization, making it valuable in building complex molecules for crop protection agents and medicinal compounds. Commonly employed in alkylation and cross-coupling reactions to introduce the pyrazole moiety into larger structures. Also utilized in research settings for the preparation of novel heterocyclic compounds with potential biological activity.
