Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of drugs that target the central nervous system. It plays a key role in creating active pharmaceutical ingredients (APIs) due to its reactive chloromethyl group, which allows for easy attachment to other molecular structures. Commonly employed in the development of antihypertensive agents and receptor antagonists. Also utilized in the preparation of agrochemicals and functionalized pyridine derivatives for research purposes. Its hydrochloride salt form improves stability and solubility, making it suitable for use in various chemical reactions under controlled conditions.
