L-LEUCINE (2-13C) is an isotopically labeled, proteinogenic amino acid belonging to the aliphatic hydrophobic amino acid class, featuring a branched side chain characteristic of leucine. The molecule contains a free α-amino group and a free carboxyl group, with the carbon at the 2-position enriched in 13C while the remaining framework retains the leucine connectivity and stereochemistry as implied by the L-designation. As an isotopically labeled tracer and analytical standard, it is used in amino acid metabolism and protein/peptide labeling studies, as well as in NMR or mass spectrometry method development where 13C incorporation at the specified position enables structural and kinetic readouts.
