Deuterated NMR Solvents

Aldrich and Isotec have shared manufacturing methods to offer a complete line of products for the NMR industry. We continually look for ways to improve our manufacturing process so we can offer you the best NMR solvent quality possible. Take a look at these NMR solvents that now have higher isotopic enrichment.

Improved DMSO-d6 Now Lower water
We have taken steps to improve the water levels in all of our DMSO listings. Order some today and experience the difference. We have also recently added DMSO-d6, 99.9 atom % D, “Special HOH”. D2O and HOD levels are kept to a minimum to avoid deuterium exchange with easily exchangeable protons in your sample.
