Acetic acid-2-13C,d4
Acetic acid-2-13C,d4 (CAS 285977-76-6) is a stable isotope-labelled form of acetic acid, carrying carbon-13 at the methyl carbon together with full deuteration, with the linear formula 13CD3CO2D and a molecular weight of about 65.07 g/mol. Supplied at 99 atom % 13C and 98 atom % D, this corrosive, flammable liquid serves chiefly as an internal standard and isotopic tracer in NMR spectroscopy, mass spectrometry and labelled-compound synthesis. Tech Serve Solutions supplies it worldwide as a research-grade reagent.

NMR internal standard and reference
The combined 13C and deuterium labelling makes this compound a useful internal standard and reference material in NMR spectroscopy. It supports quantitative and mechanistic studies where a defined isotopic signature is required.
Mass spectrometry internal standard
With a mass shift of M+5, the labelled acetic acid functions as an internal standard in mass spectrometry and isotope-dilution methods. It allows accurate quantification by distinguishing the labelled analogue from unlabelled acetic acid.
Isotopic tracer studies
As a stable isotope-labelled tracer, it is used to follow carbon and hydrogen pathways in reaction and metabolic studies. The dual 13C/D labelling provides a traceable marker without the handling constraints of radioactive isotopes.
Synthesis of labelled compounds
The reagent serves as a labelled building block for preparing 13C- and deuterium-enriched molecules and derivatives. It introduces a defined isotopic label into acetyl and related functional groups during synthesis.
Analytical and research reagent
It is employed as a research-grade reagent in analytical method development and laboratory investigation. Its well-characterised isotopic purity supports reproducible experimental work.
