2-(4-Chlorobenzenesulfonyl)-4,6-dimethyl-3-(4-methylbenzenesulfonyl)pyridine CAS 478245-48-6 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 2-(4-Chlorobenzenesulfonyl)-4,6-dimethyl-3-(4-methylbenzenesulfonyl)pyridine.

CATO supplies 2-(4-Chlorobenzenesulfonyl)-4,6-dimethyl-3-(4-methylbenzenesulfonyl)pyridine (CAS 478245-48-6), a certified reference material (molecular formula C20H18ClNO4S2, MW 435.94 g/mol) for analytical method development and quality control.

The molecular framework of 2-(4-Chlorobenzenesulfonyl)-4,6-dimethyl-3-(4-methylbenzenesulfonyl)pyridine (C20H18ClNO4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 2-(4-Chlorobenzenesulfonyl)-4,6-dimethyl-3-(4-methylbenzenesulfonyl)pyridine 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.
