Description
Compared with other compounds in its class, the molecular weight of 259.63 g/mol gives N-(3-chlorophenyl)-1,1,1-trifluoromethanesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-(3-chlorophenyl)-1,1,1-trifluoromethanesulfonamide (CAS 23384-03-4) is a high-purity analytical reference standard with the molecular formula C7H5ClF3NO2S and a molecular weight of 259.63 g/mol.
N-(3-chlorophenyl)-1,1,1-trifluoromethanesulfonamide (C7H5ClF3NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
