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 frameworks, 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 (CNS) agents. Also utilized in agrochemicals for the development of novel pesticides and herbicides due to its ability to improve compound lipophilicity and target binding.
