Description

General description

Dimethyl sulfone is a solvent, which can dissolve a wide range of solutes and can be generally used for high temperature reactions.

This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.
