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 developing drugs for the treatment of inflammatory diseases and certain cancers due to its ability to enhance selectivity and potency of active pharmaceutical ingredients. Its chiral amine structure allows for precise stereochemical control in drug design, improving metabolic stability and reducing off-target effects. Commonly employed in asymmetric synthesis and catalysis in medicinal chemistry research.
