Acetic acid-13C2
Acetic acid-13C2 (CAS 16651-47-1) is a stable carbon-13 labelled form of acetic acid in which both carbon atoms are enriched as 13C, with the molecular formula 13CH3 13CO2H and a molecular weight of 62.04 g/mol. Typically supplied at 99 atom % 13C, it is a colourless, corrosive, flammable liquid used as an isotopic tracer and internal standard in NMR, mass spectrometry and metabolic-flux studies, and as a labelled building block in synthesis.

Isotopic tracer for metabolic and flux studies
The doubly labelled 13C backbone makes Acetic acid-13C2 a sensitive tracer for following acetate and acetyl-group incorporation in metabolic and biochemical pathways. It supports stable-isotope labelling experiments where natural-abundance carbon would not be distinguishable.
NMR and mass-spectrometry reference
Enrichment at both carbons gives strong, well-defined signals, so the material is widely used in 13C NMR studies and as a labelled standard in mass spectrometry. It assists peak assignment, quantification and method development.
Labelled building block in synthesis
Acetic acid-13C2 serves as a 13C-labelled precursor for preparing acetyl groups, acetate esters and other compounds carrying defined isotopic labels. This allows the label to be carried through multi-step synthetic routes.
MRI/MRS and hyperpolarisation research
As a carbon-13 enriched substrate, it is of interest in magnetic-resonance imaging and spectroscopy (MRI/MRS) research, including studies that exploit 13C detection. Use should be confined to suitably equipped research settings.
Reference and calibration standard
The defined isotopic composition makes Acetic acid-13C2 useful as an internal standard and calibration reference in analytical laboratories. It supports quantitative work requiring an isotopically distinct analogue of acetic acid.

What is Acetic acid-13C2 used for?
+
Acetic acid-13C2 is used mainly as a stable-isotope tracer and reference material. Typical uses include 13C NMR and mass-spectrometry studies, metabolic and flux investigations, MRI/MRS research, and as a 13C-labelled building block for synthesising acetyl groups and acetate derivatives.
What is the CAS number and molecular formula of Acetic acid-13C2?
+
The CAS number is 16651-47-1 and the molecular formula is 13CH3 13CO2H (linear formula 13CH3 13CO2H), with both carbon atoms enriched as carbon-13. The molecular weight is approximately 62.04 g/mol. Its MDL number is MFCD00037367.
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies Acetic acid-13C2 as a stable-isotope research reagent, typically at an isotopic purity of 99 atom % 13C. We do not represent it as a USP, BP or EP pharmacopoeial grade; intended use is research, analytical and synthetic applications. Batch-specific isotopic and analytical data can be provided on request.
What are the safety and handling considerations for Acetic acid-13C2?
+
It is classified as Danger (GHS02, GHS05, GHS07): H226 flammable liquid and vapour, H312 harmful in contact with skin, and H314 causes severe skin burns and eye damage. Keep away from heat and ignition sources, wear protective gloves, clothing and eye/face protection, and handle with adequate ventilation. The flash point is about 40 C (104 C autoignition near 800 F), so it must be stored and used as a flammable, corrosive liquid.
How is Acetic acid-13C2 packed, shipped and exported?
+
It is supplied in appropriately sealed laboratory packaging suited to a flammable, corrosive liquid, with quantities to match research requirements. For transport it is classified as UN 2789, Class 8 (corrosive), Packing Group II, and is shipped under applicable dangerous-goods regulations. Tech Serve Solutions exports worldwide with full documentation; specific pack sizes can be confirmed at the time of enquiry.
How do I request a sample or quote for Acetic acid-13C2?
