p-Amino-L-phenylalanine hydrochloride (PABA) is a type of amino acid that is used in the synthesis of melphalan hydrochloride, a drug used to treat cancer. PABA is a white crystalline powder that can be dissolved in water and formic acid. It has been shown to interact with the hydrophilic interaction chromatography column and flow rate sensor in order to improve the chromatographic separation of ammonium formate. PABA has also been found to be chiral and can be converted into its enantiomeric form by means of an organic solvent, such as acetonitrile. The impurities of PABA are mandelic acid and l-phenylalanine. These impurities are separated from PABA by means of HPLC analysis.
