Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of central nervous system (CNS) active compounds. Its enantiomeric purity makes it valuable in developing drugs with selective biological activity, including antidepressants and anti-anxiety agents. Also employed in the preparation of beta-3 adrenergic receptor agonists for metabolic and urinary disorders. Commonly utilized in asymmetric synthesis due to its stable amine functionality and aromatic moiety, facilitating carbon-carbon bond formation in medicinal chemistry research.
