L-ALANINE (13C3, D4, 5N) is an isotopically labeled form of the proteinogenic amino acid alanine, featuring the standard amino acid backbone with a methyl side chain and stereochemistry consistent with the L-amino acid designation. The molecule contains an amino group and a carboxyl group, while its carbon, hydrogen, and nitrogen atoms are enriched with 13C, deuterium (D), and 15N (5N), respectively, enabling mass-shifted detection without altering the overall functional-group connectivity. L-ALANINE (13C3, D4, 5N) is used in isotopic tracing, quantitative mass spectrometry and NMR method development, and peptide or protein labeling workflows where alanine-derived fragments are monitored with the labeled isotopes.
