Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its reactive chloromethyl group allows for easy functionalization, making it valuable in building complex heterocyclic compounds. Commonly employed in agrochemical research for creating novel pesticides and fungicides due to the stability and bioactivity of the isoxazole ring. Also utilized in medicinal chemistry for structure-activity relationship studies, where it helps modify drug candidates to enhance potency, solubility, or metabolic stability.
