Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and receptor-targeted drugs. Its bromo and methoxy functional groups allow for further cross-coupling reactions, enabling structural diversification. The amine group, often protected or modified, facilitates peptide-like linkages or salt formation to improve solubility and bioavailability. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its stereochemical purity and aromatic substitution pattern.
