L-Phenylalanine, CAS # 63-91-2, is an essential amino acid with an aromatic structure used in the biosynthesis of other amino acids. It is important for the structure and function of many proteins and enzymes.

L-Phenylalanine is an aromatic organic compound containing amine and acid as functional groups. It is an essential amino acid and its structure can be considered as the derivative of 3-phenylpropionic acid, in which one hydrogen atom present at C-2 position is substituted with amino group. It is a chiral compound and consists of two optical isomers. It is also known as 2-amino-3-phenylpropanoic acid, beta-phenylalanine, L-alfa-amino-beta-phenylpropionic acid, H-Phe-OH and (S)-2-amino-3-phenylpropionic acid.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
