Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and calcium channel blockers. Its reactive chloromethyl group allows for easy alkylation and functionalization, making it valuable in constructing complex organic molecules. Commonly employed in research and development of bioactive compounds, including antifungal and anticancer agents. Also utilized in agrochemical synthesis for developing novel pesticides and herbicides due to its furan ring structure, which can enhance biological activity.
