Beschrijving
Deuterium oxide is a high-enrichment heavy water reagent supplied at 99,9 Atom%D for demanding spectroscopic and isotope-exchange work. Identified by CAS number 7789-20-0 and EG nr. 232-148-9, it has the empirical formula D₂O, a molar mass of 20,03 g/mol and a density of 1,104 g/cm³. The boiling point lies between 101 and 102 °C, supporting controlled handling in analytical and preparative settings. This 10 ml glass pack is intended for nuclear magnetic resonance spectroscopy and related spectrometry applications where a deuterated solvent or exchange medium is required. Laboratories use deuterium oxide to prepare NMR samples, lock solvents and isotope-labelled systems with consistent isotopic purity. The material is offered from manufacturer Carl ROTH as a compact laboratory unit suited to method development, reference preparation and routine NMR workflows. Clear physical data and defined isotopic enrichment help ensure reproducible results across spectroscopy and molecular characterisation protocols.
This article is part of Dry & deuterated solvents (NMR, synthesis), in Solvents.

Questions about Deuterium oxide, 99,9 Atom%D, 10 ml
What is this article?
Deuterium oxide, 99,9 Atom%D, 10 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dry & deuterated solvents (NMR, synthesis), inside Solvents, in Chemicaliën.
A dry solvent has had water removed to a stated level, for a reaction that water would stop. A deuterated solvent replaces hydrogen with deuterium so an NMR spectrum is not drowned by the solvent signal. The isotopic enrichment and the water content are the two specifications. Caps and septa matter, because either product picks up moisture from the air.
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 Dry & deuterated solvents (NMR, synthesis). The catalogue is Chemicaliën.
