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 bromo and fluoro substituents, making it suitable for further functionalization via cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations. Commonly employed in the preparation of central nervous system agents and kinase inhibitors due to its ability to enhance binding selectivity and metabolic stability. The presence of the chiral amine center allows for asymmetric synthesis routes, enabling the production of enantiomerically pure drugs.
