2,3,5,6-Tetrafluoro-4-(trifluoromethyl)benzenesulfonyl chloride CAS 40586-68-3

Description

Compared with other compounds in its class, the molecular weight of 316.58 g/mol gives 2,3,5,6-Tetrafluoro-4-(trifluoromethyl)benzenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3,5,6-Tetrafluoro-4-(trifluoromethyl)benzenesulfonyl chloride (CAS 40586-68-3), molecular formula C7ClF7O2S and molecular weight 316.58 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, fluorine/chlorine substitution, an aromatic ring system, 2,3,5,6-Tetrafluoro-4-(trifluoromethyl)benzenesulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
