Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 332.32 g/mol gives S-(Trifluoromethyl)dibenzothiophenium-3-sulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies S-(Trifluoromethyl)dibenzothiophenium-3-sulfonate (CAS 160656-62-2), a certified reference material (molecular formula C13H7F3O3S2, MW 332.32 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, S-(Trifluoromethyl)dibenzothiophenium-3-sulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
