Acetic acid-17O2
Acetic acid-17O2 (CAS 57745-60-5) is an oxygen-17 stable-isotope-labelled form of glacial acetic acid, molecular formula CH3C(17O2)H and molecular weight approximately 62.05 g/mol, supplied at 20 atom % 17O. It is a clear, corrosive, flammable liquid carrying the carboxylic-acid functionality of ordinary acetic acid with both carbonyl oxygens enriched in the NMR-active 17O nucleus. Tech Serve Solutions supplies it as a research-grade isotopic reagent for tracer, mechanistic and spectroscopic studies.

Oxygen-17 NMR spectroscopy
The 17O enrichment makes this reagent valuable for 17O NMR studies, where the spin-active oxygen nucleus is otherwise present at very low natural abundance. It supports investigation of carboxyl oxygen environments, hydrogen bonding and exchange behaviour.
Isotopic labelling and tracer studies
Oxygen-17 enrichment provides a stable, non-radioactive label for following the fate of carboxyl oxygen atoms through chemical and biochemical transformations. It is used to probe reaction pathways and oxygen-transfer processes.
Reaction mechanism investigation
As a labelled analogue of a common organic acid, it serves in mechanistic chemistry to track esterification, hydrolysis and acyl-transfer reactions. The isotopic marker helps distinguish competing pathways without altering the underlying chemistry.
Reference and method-development standard
The defined 17O content and well-characterised physical properties suit it as a reference material for developing and calibrating analytical and spectroscopic methods. It is intended strictly for laboratory and research use.

What is Acetic acid-17O2 used for?
+
Acetic acid-17O2 is used principally as a stable-isotope research reagent. Its 17O enrichment supports oxygen-17 NMR spectroscopy, isotopic labelling and tracer experiments, and mechanistic studies of esterification, hydrolysis and acyl-transfer reactions. It is intended for laboratory and research applications, not consumer use.
What is the CAS number and molecular formula of Acetic acid-17O2?
+
The CAS number is 57745-60-5 and the molecular formula is CH3C(17O2)H, the oxygen-17 labelled form of acetic acid. The molecular weight is approximately 62.05 g/mol, and the material is supplied at 20 atom % 17O. The MDL number is MFCD01075638.
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies Acetic acid-17O2 as a research-grade isotopic reagent with an isotopic enrichment of 20 atom % 17O. We do not represent this product as USP, BP or EP pharmacopoeial grade. Current isotopic and analytical specifications are confirmed on the certificate of analysis for each batch.
What are the safety and handling requirements for Acetic acid-17O2?
+
It is classified as a flammable liquid and is corrosive (GHS02, GHS05; signal word Danger; H226 and H314), causing severe skin burns and eye damage. Keep away from heat, sparks and open flame, and handle with chemical-resistant gloves, goggles, faceshield and suitable respiratory protection in a well-ventilated area. Always consult the Safety Data Sheet before use.
How is Acetic acid-17O2 packed, shipped and exported?
+
Because of its high cost and isotopic value, it is supplied in small sealed laboratory units with tamper-evident packaging and full documentation. It is classed as a corrosive substance for transport (UN 2789, Class 8, Packing Group II) and is shipped in compliance with applicable dangerous-goods regulations. We export worldwide with the appropriate documentation.
How do I request a sample or quote?
+
Contact Tech Serve Solutions with the product name, CAS number 57745-60-5, your required quantity and intended research application, and our team will confirm availability, isotopic specification, lead time and export terms. We will provide a Safety Data Sheet and certificate of analysis on request.
