Used in pharmaceutical synthesis as a chiral building block for developing active pharmaceutical ingredients (APIs), particularly in the production of neurologically active compounds. Its stereochemistry makes it valuable in creating enantioselective drugs, where specific 3D orientation is critical for biological activity. Commonly employed in research and development of medications targeting central nervous system disorders. Also utilized in asymmetric synthesis to introduce chiral centers in complex molecules. The tartarate salt form enhances stability and crystallinity, facilitating purification and handling during manufacturing processes.
