Description
L-Proline-¹³C₅ is a stable-isotope-labelled amino acid offered at a minimum purity of 95 % with a molar mass of 120,13 g/mol (CAS 201740-83-2). Its empirical formula is ¹³C₅H₉NO₂, indicating uniform ¹³C enrichment across the five carbon atoms of the L-proline skeleton. Supplied in a 5 mg pack, this reagent is intended for analytical and metabolic research where mass-shifted proline is required as an internal standard, tracer, or labelled building block. The material is available from manufacturer Carl ROTH for laboratories working in LC-MS, GC-MS, NMR-related workflows, and isotope-dilution methods. The defined molar mass and high minimum purity support accurate preparation of calibration solutions and spike mixes at low absolute consumption. Researchers use L-Proline-¹³C₅ in quantitative proteomics and metabolomics, pathway tracing, and method validation that depend on a fully ¹³C-labelled proline isotopologue. Compact packaging suits precious labelled standards and reduces waste during method development. With clear CAS identity, scientific formula notation, and a practical milligram-scale unit, this product fits specialised biochemical and analytical applications requiring reliable ¹³C₅-labelled L-proline.

Questions about L-Proline-¹³C5
What is this article?
L-Proline-¹³C5 is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Amino acids & peptides, inside Biochemicals & reagents, in Microbiology lab supplies.
An amino acid or a peptide is specified by the sequence or the residue, the chirality, and for a peptide the purity and the salt form. L and D forms are different compounds. A trifluoroacetate salt and a hydrochloride salt weigh differently per mole of peptide.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
