1-({2-[(4-chlorophenyl)sulphonyl]ethyl}thio)-2,3,4,5,6-pentafluorobenzene (C14H8ClF5O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-({2-[(4-chlorophenyl)sulphonyl]ethyl}thio)-2,3,4,5,6-pentafluorobenzene (CAS 649578-39-2), molecular formula C14H8ClF5O2S2 and molecular weight 402.79 g/mol, is a CATO reference standard with documented purity and traceability.
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.
