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 constructing heterocyclic compounds for drug discovery. Commonly employed in coupling reactions to introduce the isoxazole moiety into larger molecules, enhancing metabolic stability and bioavailability. Also utilized in agrochemical research for designing novel pesticides due to its favorable reactivity and structural properties.
