Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 2-Hydroxy-5-((5-oxo-6-phenyl-4,5-dihydro-1,2,4-triazin-3-yl)amino)benzoic acid (CAS 1417635-98-3), a certified reference material (molecular formula C16H12N4O4, MW 324.29 g/mol) for analytical method development and quality control.
The molecular framework of 2-Hydroxy-5-((5-oxo-6-phenyl-4,5-dihydro-1,2,4-triazin-3-yl)amino)benzoic acid (C16H12N4O4) is characterized by a flavonoid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
