Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 138.14 g/mol gives Glycerol Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Glycerol Impurity 13 (CAS 13897-37-5), molecular formula C3H6O4S and molecular weight 138.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, an ether linkage, Glycerol Impurity 13 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
