摘要
Quantitative nuclear magnetic resonance (QNMR) is a primary analytical method which allows the use of a standard not directly related to the target analyte. This could allow the introduction of a single universal reference material (URM) to which all other organic standard reference materials/certified reference materials may be compared. Dimethylsulfone is a simple substance that fulfils all criteria necessary as the URM to which the QNMR analysis of all other organic substances may be referenced and hence we propose this as a candidate for this purpose.
