Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of selective kinase inhibitors. It plays an important role in the development of drugs targeting inflammatory diseases and certain cancers due to its ability to enhance selectivity and potency in the final active compound. Its chiral amine structure allows for precise stereochemical control during drug synthesis, improving metabolic stability and reducing unwanted side effects. Commonly employed in research and development for oral medications where high enantiomeric purity is required.
