DL-LEUCINE (2-13C) is a stable-isotope-labeled leucine derivative in which the carbon at the 2-position is enriched with 13C, and it is supplied as the DL (racemic) mixture of amino acid enantiomers. The molecule contains a free primary amino group and a free carboxylic acid, with a hydrophobic isobutyl side chain characteristic of leucine and no additional protecting groups or derivatization. It is used as an isotopically labeled amino acid for 13C-based tracing, metabolic and turnover studies, and analytical method development where incorporation of the labeled carbon into peptides, metabolites, or other downstream analytes is monitored by NMR or mass spectrometry.
