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 5-(Benzenesulfonyl)-4-(2,4-dichlorophenyl)-2-(pyridin-3-yl)pyrimidine.
CATO supplies 5-(Benzenesulfonyl)-4-(2,4-dichlorophenyl)-2-(pyridin-3-yl)pyrimidine (CAS 339108-13-3), a certified reference material (molecular formula C21H13Cl2N3O2S, MW 442.32 g/mol) for analytical method development and quality control.
The molecular framework of 5-(Benzenesulfonyl)-4-(2,4-dichlorophenyl)-2-(pyridin-3-yl)pyrimidine (C21H13Cl2N3O2S) is characterized by a steroid 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.
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.
