Description
L-Arginine 13C₆ 15N₄ monohydrochloride is a dual stable-isotope-labelled amino acid salt with CAS number 202468-25-5 and empirical formula ¹³C₆H₁₄¹⁵N₄O₂·HCl. Offered at a minimum of 98 % ¹³C and ¹⁵N enrichment, it has a molar mass of 216,7 g/mol and is packed as 100 mg in plastic. This heavily labelled arginine derivative is intended for advanced tracer, SILAC-type and quantitative mass-spectrometry experiments that require simultaneous carbon-13 and nitrogen-15 labelling. Supplied by manufacturer Carl ROTH, the monohydrochloride supports metabolic flux analysis, protein quantification and internal-standard strategies in proteomics and systems biology. Dual isotopic enrichment improves mass shift and spectral discrimination compared with single-label analogues, aiding confident peak assignment. Laboratories can incorporate this reagent into labelling media, spike mixes or calibration workflows where defined ¹³C₆¹⁵N₄ arginine is specified. Documented CAS, formula and molar-mass data simplify compliance, ordering and method transfer across research and analytical settings.

Questions about L-Arginine 13C6 15N4 monohydrochloride, min. 98 % 13C 15N, 100 mg, plastic
What is this article?
L-Arginine 13C6 15N4 monohydrochloride, min. 98 % 13C 15N, 100 mg, plastic 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.
