Chemical Structure
Description
As a certified reference material (CRM), N-(3-chloro-4-(2,6-dinitro-4-(trifluoromethyl)phenoxy)phenyl)-4-methylbenzenesulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
N-(3-chloro-4-(2,6-dinitro-4-(trifluoromethyl)phenoxy)phenyl)-4-methylbenzenesulfonamide (CAS 338413-12-0), molecular formula C20H13ClF3N3O7S and molecular weight 531.85 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, N-(3-chloro-4-(2,6-dinitro-4-(trifluoromethyl)phenoxy)phenyl)-4-methylbenzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 531.85 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.
