CATO supplies 4-((5-Cyano-6-hydroxy-4-methyl-2-oxo-1,2-dihydropyridin-3-yl)diazenyl)benzoic acid (CAS 796874-80-1), a certified reference material (molecular formula C14H10N4O4, MW 298.25 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-((5-Cyano-6-hydroxy-4-methyl-2-oxo-1,2-dihydropyridin-3-yl)diazenyl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-((5-Cyano-6-hydroxy-4-methyl-2-oxo-1,2-dihydropyridin-3-yl)diazenyl)benzoic acid 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.
