Description
Methanol D₄ is a deuterated NMR solvent with 99,8 Atom%D isotopic enrichment, empirical formula CD₃OD and CAS number 811-98-3. It has a molar mass of 36,07 g/mol, a density of 0,89 g/cm³, a boiling point of 65 °C and a flash point of 11 °C, making it suitable for high-resolution nuclear magnetic resonance work where residual proton background must stay low. This grade is supplied in a 10 ml glass pack for convenient bench use in spectroscopy and spectrometry laboratories. The EG number is 212-378-6. Mid-scale analytical and research groups often select this deuterated methanol from manufacturer Carl ROTH when preparing samples, locking field frequency or running routine ¹H and multinuclear NMR experiments. Its defined physical constants support reproducible solvent handling and method transfer across instruments. Categories of use centre on compounds for NMR within broader spectroscopy workflows, where consistent Atom%D purity and clear identity data help maintain spectral quality from sample preparation through data acquisition.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Methanol D4, 99,8 Atom%D, 10 ml
What is this article?
Methanol D4, 99,8 Atom%D, 10 ml 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.
