Used primarily as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring stereochemical control. Its amine functionality and chiral center make it valuable in asymmetric synthesis, where it serves as an intermediate in the production of central nervous system agents, including certain antipsychotics and antidepressants. The dihydrochloride salt form enhances stability and solubility, facilitating handling and purification during manufacturing processes. It is also employed in research settings for the preparation of novel bioactive compounds and in medicinal chemistry for structure-activity relationship (SAR) studies.
