Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure contains both amine and halogen functionalities, making it suitable for coupling reactions in drug design. Commonly applied in the production of central nervous system agents and anti-inflammatory compounds. Due to its enantiomeric purity, it is valuable in asymmetric synthesis to ensure desired efficacy and safety profiles in final drug products.
