Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its enantiomeric purity makes it valuable for creating selective serotonin or dopamine receptor modulators. The bromine substituent at the 4-position, along with the amine functionality, enables diverse synthetic transformations, such as nucleophilic substitutions or cross-coupling reactions to form carbon-carbon bonds. Commonly employed in asymmetric synthesis to introduce chirality in drug candidates. Also utilized in the preparation of intermediates for neurodegenerative disease treatments, such as Parkinson’s and Alzheimer’s. Its amine group allows for easy derivatization in peptide-like structures or small molecule drugs.
