Acetic acid-d4
Acetic acid-d4 (CAS 1186-52-3) is the fully deuterated form of glacial acetic acid, with the formula CD3CO2D and a molecular weight of 64.08 g/mol. Tech Serve Solutions supplies it as a high-purity deuterated NMR solvent at 99.5 atom % D, typically containing 0.03 % (v/v) TMS as an internal reference. A clear, corrosive, flammable liquid, it is used chiefly as a lock solvent in NMR spectroscopy and in isotope-labelling and mechanistic chemistry.

Deuterated NMR solvent
Serves as a deuterium-locked solvent for 1H, 13C and multinuclear NMR spectroscopy, dissolving acid-stable and polar samples while suppressing the solvent proton signal. The 99.5 atom % D isotopic purity provides a clean deuterium lock and minimal residual solvent peak.
Biomolecular and structural NMR
Used in biomolecular NMR and buffer or reagent preparation where an acidic, deuterated medium is required. It supports studies of peptides, small molecules and other analytes that benefit from a low-pH deuterated environment.
Isotope labelling and tracer studies
Acts as a source of deuterium for hydrogen/deuterium exchange and isotopic labelling. The M+4 mass shift makes it useful in mass-spectrometry-supported tracer and metabolic studies.
Reaction-mechanism and kinetic studies
Employed in chemical synthesis and physical-organic chemistry to probe reaction mechanisms and kinetic isotope effects, where the deuterated acidic proton and methyl group can be tracked spectroscopically.

+
Acetic acid-d4 has CAS number 1186-52-3 and the molecular formula CD3CO2D (linear formula CD3CO2D). Its molecular weight is 64.08 g/mol, with an M+4 mass shift; the MDL number is MFCD00051051 and the EC number is 214-693-4.
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies Acetic acid-d4 as a research-grade deuterated NMR solvent with an isotopic purity of 99.5 atom % D, typically containing 0.03 % (v/v) TMS. We do not represent this material as USP, BP or EP pharmacopoeial grade. A certificate of analysis can be provided with each batch.
What are the safety and handling requirements for Acetic acid-d4?
+
Acetic acid-d4 is classified as a flammable liquid and is corrosive (GHS02, GHS05; signal word Danger; hazard statements H226 and H314). It causes severe skin burns and eye damage and has a flash point of 40 C. Handle away from heat and ignition sources, with goggles, face protection, gloves and suitable respiratory protection, and follow the precautionary statements P280, P305+P351+P338 and P310. WGK (Germany) is 3.
How is Acetic acid-d4 packed, shipped and exported?
+
It is supplied in sealed, inert, moisture-protected glass packaging appropriate to a hygroscopic, corrosive deuterated solvent, in laboratory and bulk sizes to suit your requirement. As a Class 8 corrosive that is also flammable, it is shipped under UN 2789 (packing group II) with compliant dangerous-goods documentation for domestic and international export.
