Description

Compared with other compounds in its class, the molecular weight of 200.18 g/mol gives 6-(Trifluoromethyl)-3,4-dihydro-2H-thiopyran 1,1-dioxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-(Trifluoromethyl)-3,4-dihydro-2H-thiopyran 1,1-dioxide (CAS 2137895-44-2), molecular formula C6H7F3O2S and molecular weight 200.18 g/mol, is a CATO reference standard with documented purity and traceability.

6-(Trifluoromethyl)-3,4-dihydro-2H-thiopyran 1,1-dioxide (C6H7F3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
