L-ALLO-ISOLEUCINE (13C6,D10,15N) is an isotopically labeled, non-proteinogenic amino acid derivative related to isoleucine, bearing an aliphatic side chain with a branched carbon skeleton and an α-amino acid backbone. The molecule contains an amino group and a carboxyl group, with six 13C atoms, ten deuterium atoms, and one 15N atom incorporated into the framework as indicated by the product name, enabling mass-shifted analytical detection relative to unlabeled analogues. It is used in isotopic tracing, quantitative amino acid analysis, and peptide or metabolite labeling workflows where the labeled side chain and backbone support tracking by mass spectrometry or related analytical methods.
