L-ALANINE (2-13C) is an isotopically labeled, free amino acid belonging to the aliphatic amino acid class, featuring an unprotected α-amino group and a carboxylic acid group attached to a methyl side chain bearing a 13C label at the 2-position of the alanine skeleton. The molecule exists as the L-stereochemical form as indicated by its name, and it contains the characteristic primary amine and carboxyl functionalities that can undergo standard amino-acid derivatization and acid-base equilibria in solution. L-ALANINE (2-13C) is used in isotopic tracing, NMR or mass spectrometric method development, and peptide or biochemical labeling workflows where incorporation or detection of the 13C label at the alanine backbone position is required.
