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 Sodium 6-hydroxy-4-methyl-2-oxo-1,2-dihydropyridine-3-carbonitrile.
CATO supplies Sodium 6-hydroxy-4-methyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (CAS 39120-56-4), a certified reference material (molecular formula C7H5N2O2Na, MW 172.12 g/mol) for analytical method development and quality control.
The molecular framework of Sodium 6-hydroxy-4-methyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (C7H5N2O2Na) 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).
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), Sodium 6-hydroxy-4-methyl-2-oxo-1,2-dihydropyridine-3-carbonitrile 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.
