Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihistamines and local anesthetics. It also serves in the preparation of agrochemicals and functionalized polymers due to its reactive amine and chloro groups. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous reaction systems. Additionally, it finds application in the development of specialty chemicals such as surfactants and corrosion inhibitors.
