(R)-α-Aminobenzeneacetic acid
(R)-α-Aminobenzeneacetic acid, also known as D-phenylglycine, is a chiral aromatic amino acid featuring both amino and carboxylic acid oxygen functions on a benzene ring. It falls under HTS 2922.49.0500 as a specific aromatic amino acid with a single type of oxygen function (carboxyl group). This compound is primarily used as a key intermediate in synthesizing beta-lactam antibiotics like ampicillin.
