Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methanesulfonyl-6-(pyridin-2-yl)-2,2'-bipyridine.
4-Methanesulfonyl-6-(pyridin-2-yl)-2,2'-bipyridine (CAS 81874-51-3), molecular formula C16H13N3O2S and molecular weight 311.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Methanesulfonyl-6-(pyridin-2-yl)-2,2'-bipyridine (C16H13N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
CATO manufactures 4-Methanesulfonyl-6-(pyridin-2-yl)-2,2'-bipyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
