Description
Methanol D₄ is a fully deuterated methanol solvent supplied at 100 Atom%D for nuclear magnetic resonance spectroscopy and related analytical work. With CAS number 811-98-3 and empirical formula CD₃OD, it offers a molar mass of 36,07 g/mol and a density of 0,89 g/cm³. The material boils at 65 °C and has a flash point of 11 °C, supporting controlled handling in standard laboratory environments. This grade is Physical data align with typical deuterated methanol behaviour, making the solvent suitable for sample preparation, lock solvents, and reference work in spectroscopy laboratories. The product is available from manufacturer Carl ROTH as part of its NMR compounds range. Methanol D₄ is commonly selected when residual solvent peaks must be kept low and when reproducible deuterium content is required across analytical runs. Its defined Atom%D specification, compact glass pack size, and well-characterised boiling and density values support routine use in research, quality control, and method development settings that rely on nuclear magnetic resonance.

Questions about Methanol D4, 100 Atom%D, 7.5 ml, glass ampoule
What is this article?
Methanol D4, 100 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?
