Sodium (5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitrobenzoyl)(methylsulfonyl)amide (CAS 108731-70-0), molecular formula C15H9ClF3N2O6SNa and molecular weight 460.74 g/mol, is a CATO reference standard with documented purity and traceability.
Sodium (5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitrobenzoyl)(methylsulfonyl)amide (C15H9ClF3N2O6SNa) contains a salt form, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
