4-(Benzenesulfonyl)-N-(3-chloro-4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)-4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]butanamide CAS 338407-43-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Benzenesulfonyl)-N-(3-chloro-4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)-4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]butanamide.

CATO supplies 4-(Benzenesulfonyl)-N-(3-chloro-4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)-4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]butanamide (CAS 338407-43-5), a certified reference material (molecular formula C28H19Cl2F6N3O4S, MW 678.43 g/mol) for analytical method development and quality control.

4-(Benzenesulfonyl)-N-(3-chloro-4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)-4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]butanamide (C28H19Cl2F6N3O4S) contains a steroid 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4-(Benzenesulfonyl)-N-(3-chloro-4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)-4-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]butanamide 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.
