Application

Deuterium oxide (Heavy water, Water-d2, D2O) has been used as solvent for the dissolution of internal standard and sample during quantification experiments by NMR. It has been used for the dissolution of tris(2,2′-bipyridyl)dichlororuthenium(II) hexahydrate Ru(bpy)3.4

General description

Deuterium oxide, a deuterated solvent, is a standard prurity solvent for NMR (Nuclear Magnetic Resonance) analyses. Various thermodynamic properties (such as intermolecular vibrational frequencies, energy of the hydrogen bond, free energy, enthalpy and entropy) of liquid deuterium oxide have been evaluated. Ionization constant for D2O (in the range of 5-50°C), pK values (at 25°C) and enthalpy, entropy, heat capacity change (for the dissociation of D2O) have been reported.

Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis. These documents are located on the product detail page under Useful Links & Tools. Click on the following link to search for a Certificate of Analysis. Please click the following link to see the details on our Product Dating Information.
How do I get lot-specific information or a Certificate of Analysis?
A Certificate of Analysis is available by lot number and can be obtained through our Advanced Search Option: http://www.sigmaaldrich.com/catalog/AdvancedSearchPage.do
Where can I see a list of other NMR solvents?
You can browse our NMR solvent listing at the following link: http://www.sigmaaldrich.com/catalog/search/TablePage/12544037
How should I store Product 151882, Deuterium oxide, to preserve its purity?
According to our MSDS, deuterium oxide is classified as hygroscopic and should be stored under an inert gas like nitrogen, to prevent hydrogenated water uptake.
I don't have the ability to store Product 151882, Deuterium oxide, under nitrogen to prevent H2O uptake. Is there another way that I can work with D20 in order to preserve its purity?
You may be interested in our ampulized deuterium oxide products: 521965 (10x0.6mL), 441376 (10x0.75mL) or 269794 (10x1mL). These products are ideal for one time use applications, like as an NMR solvent, because there is decreased chance of water uptake during storage.
How do I find price and availability?
There are several ways to find pricing and availability for our products.  Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers. 
What is the Department of Transportation shipping information for this product?
