Used primarily as a key intermediate in the synthesis of pharmaceuticals, especially in the production of certain antidepressants and central nervous system agents. Its structure allows for the development of active compounds that modulate neurotransmitter activity. It is also employed in research settings for the preparation of analogs in medicinal chemistry due to its reactive ketone and amine functionalities. The hydrochloride salt form improves stability and solubility, making it suitable for use in controlled synthetic processes.
