Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its reactive chloromethyl group allows for easy alkylation and coupling reactions, making it valuable in building complex heterocyclic systems. Commonly employed in research laboratories for the preparation of pyrazole-based bioactive molecules with potential insecticidal or fungicidal properties. Also utilized in medicinal chemistry for structure-activity relationship studies due to the stability and versatility of the pyrazole core.
