Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(E)-N-Hydroxy-N'-(4-methyl-5-nitropyridin-2-yl)formimidamide (CAS 2230820-23-0) is a high-purity analytical reference standard with the molecular formula C7H8N4O3 and a molecular weight of 196.16 g/mol.
The molecular framework of (E)-N-Hydroxy-N'-(4-methyl-5-nitropyridin-2-yl)formimidamide (C7H8N4O3) is characterized by an amino-acid-derived structure, an amide 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).
CATO manufactures (E)-N-Hydroxy-N'-(4-methyl-5-nitropyridin-2-yl)formimidamide 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.
