Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of pyrazole-based active ingredients. Its structure allows for easy functionalization, making it valuable in developing herbicides and plant growth regulators. Also employed in medicinal chemistry for constructing heterocyclic compounds with potential biological activity, including anti-inflammatory and antimicrobial agents. Commonly utilized in research settings for designing new chemical entities requiring a chlorinated pyrazole moiety linked to an acetic acid functionality.
