(S)-3-tert-Butoxycarbonylamino-2-(4-chlorophenyl)propionic acid（Cat No.:L006547）is a chiral amino acid derivative featuring a (S)-configured center, a 4-chlorophenyl substituent, and a tert-butoxycarbonyl (Boc) protecting group on the amino function. This compound is commonly used in peptide synthesis and medicinal chemistry as a building block for bioactive molecules. The Boc group provides protection under basic conditions and can be removed under mild acid to reveal the free amine. The 4-chlorophenyl ring contributes to hydrophobic interactions and electronic effects in drug design. Its stereochemistry is essential for applications in enantioselective synthesis and pharmaceutical development.
