Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihistamines and antidepressants. Its structure allows for the development of bioactive molecules that interact with central nervous system receptors. Commonly employed in research settings for the preparation of analogs in drug discovery programs. Also utilized in the development of agrochemicals due to its reactivity and functional group compatibility. The hydrochloride salt form enhances stability and solubility, making it suitable for further chemical transformations in industrial and laboratory applications.
