Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated pyridine-based drugs. Its reactive chloromethyl group allows for easy attachment to other molecular structures, making it valuable in creating active pharmaceutical ingredients (APIs) with enhanced metabolic stability and bioavailability. Commonly employed in the production of kinase inhibitors and central nervous system agents. Also utilized in agrochemicals for the development of herbicides and insecticides due to its ability to improve compound selectivity and potency.
