Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs. Its chiral morpholine structure makes it valuable in creating compounds with high selectivity and potency. Commonly employed in the production of antidepressants and antipsychotics due to its ability to modulate neurotransmitter activity. Also utilized in research settings for structure-activity relationship (SAR) studies to optimize drug candidates. The hydrochloride salt form enhances stability and solubility, facilitating its use in various reaction conditions and purification processes.
