Chemical Structure
Description
4-Hydroxytetrahydro-2H-thiopyran 1,1-Dioxide (CAS 194152-05-1), molecular formula C5H10O3S and molecular weight 150.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 4-Hydroxytetrahydro-2H-thiopyran 1,1-Dioxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.20 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.
