Chemical Structure
Description
6-Amino-2-methoxy-5-(4-methylbenzenesulfonyl)pyridine-3-carbonitrile (CAS 338774-42-8) is a high-purity analytical reference standard with the molecular formula C14H13N3O3S and a molecular weight of 303.34 g/mol.
The molecular framework of 6-Amino-2-methoxy-5-(4-methylbenzenesulfonyl)pyridine-3-carbonitrile (C14H13N3O3S) 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 6-Amino-2-methoxy-5-(4-methylbenzenesulfonyl)pyridine-3-carbonitrile 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.
