Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrazole-based drugs with anti-inflammatory and analgesic properties. Its reactive chloromethyl group allows for easy functionalization, making it valuable in constructing more complex molecules for drug discovery. Also employed in agrochemical research for designing novel pesticides and herbicides due to its stable aromatic and heterocyclic framework. Commonly utilized in organic synthesis to introduce the 4-(chloromethyl)phenyl pyrazole moiety into target compounds.
