Compared with other compounds in its class, the molecular weight of 494.33 g/mol gives 3-[(2,6-Dichlorophenyl)methanesulfonyl]-N-[4-(trifluoromethyl)phenyl]thiophene-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-[(2,6-Dichlorophenyl)methanesulfonyl]-N-[4-(trifluoromethyl)phenyl]thiophene-2-carboxamide (CAS 251097-09-3) is a high-purity analytical reference standard with the molecular formula C19H12Cl2F3NO3S2 and a molecular weight of 494.33 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-[(2,6-Dichlorophenyl)methanesulfonyl]-N-[4-(trifluoromethyl)phenyl]thiophene-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 494.33 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.
