Used as a key intermediate in the synthesis of agricultural chemicals, particularly in the production of herbicides and fungicides. Its structure allows for easy functionalization, making it valuable in developing active ingredients that target specific plant enzymes or fungal pathways. Also utilized in the preparation of pharmaceuticals where the pyrazole core contributes to biological activity. Commonly employed in research settings for building more complex heterocyclic systems due to its reactive chloromethyl group, which readily undergoes nucleophilic substitution reactions.
