Description
Methanol D₄ with TMS (0,03 Vol.%) is a deuterated NMR solvent offering 99,8 Atom%D enrichment together with a defined tetramethylsilane reference additive. Identified by CAS number 811-98-3 and empirical formula CD₃OD, it has a molar mass of 36,07 g/mol and a density of 0,89 g/cm³. Boiling point is 65 °C and flash point is 11 °C, consistent with methanol-based deuterated media used in spectroscopic laboratories. %. TMS, enabling convenient chemical-shift referencing without separate internal standard addition. It is suited to nuclear magnetic resonance workflows where residual proton background must remain low and a stable reference signal is required. The product comes from manufacturer Carl ROTH and fits routine sample preparation for organic and analytical NMR. Laboratories use methanol-d4/TMS blends for lock solvent duties, structure elucidation support, and quality-control spectra. The stated Atom%D level, compact glass format, and documented physical properties help ensure reproducible results across research and industrial analytical environments that depend on clear, well-referenced NMR data.

Questions about Methanol D4 with TMS (0,03 Vol.%), 99,8 Atom%D, 7.5 ml, glass ampoule
What is this article?
Methanol D4 with TMS (0,03 Vol.%), 99,8 Atom%D, 7.5 ml, glass ampoule is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
