Description
L-Valine-13C₅ is a carbon-13 labelled amino acid offered at a minimum purity of 95 %, with CAS number 55443-52-2. The empirical formula is (¹³CH₃)₂¹³CH¹³CH(NH₂)¹³COOH and the molar mass is 122,11 g/mol. Five ¹³C atoms are incorporated into the carbon skeleton, producing a clear mass shift that supports quantitative mass spectrometry, metabolic flux analysis, and NMR-based pathway studies. The material is well suited as a labelled standard or tracer in metabolomics, protein turnover work, and stable-isotope labelling workflows where defined enrichment of the branched-chain amino acid valine is required. Available from manufacturer Carl ROTH, the product fits method development and routine assays in proteomics and systems-biology settings. Its compact pack size helps conserve material during method optimisation while still providing enough reagent for multiple analytical runs under controlled laboratory conditions.

Questions about L-Valine-13C5, min. 95 %, 5 mg
What is this article?
L-Valine-13C5, min. 95 %, 5 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Biochemicals & reagents, in Microbiology lab supplies.
Click and bioconjugation reagents join two molecules under mild conditions, often an azide to an alkyne, or an NHS ester to an amine. The linker length and the reactive group are the specification. They are small bottles of a reactive compound, and moisture often ruins them.
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.
