Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (methanesulfonyloxy)methyl methanesulfonate (CAS 156-72-9), a certified reference material (molecular formula C3H8O6S2, MW 204.22 g/mol) for analytical method development and quality control.
Based on its molecular formula C3H8O6S2, (methanesulfonyloxy)methyl methanesulfonate contains a sulfone group, a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 204.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
