Used primarily as a key intermediate in the synthesis of pyrazole-based pharmaceuticals and agrochemicals. Its structure supports the development of compounds with biological activity, particularly in fungicides and herbicides. The carboxylic acid group allows for easy derivatization, enabling the formation of amides, esters, or salts that enhance bioavailability or target specificity. Commonly employed in research settings for designing new active ingredients in crop protection agents due to the electron-withdrawing chloro-substituents that improve stability and binding affinity. Also explored in medicinal chemistry for potential anti-inflammatory or antimicrobial agents.
