CATO supplies 2-(3-Methyl-1H-imidazol-3-ium-1-yl)-5-nitropyridine 1-oxide 4-methylbenzenesulfonate (CAS 66809-39-0), a certified reference material (molecular formula C9H9N4O3C7H7O3S, MW 392.39 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Methyl-1H-imidazol-3-ium-1-yl)-5-nitropyridine 1-oxide 4-methylbenzenesulfonate (C9H9N4O3C7H7O3S) is characterized by a flavonoid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 2-(3-Methyl-1H-imidazol-3-ium-1-yl)-5-nitropyridine 1-oxide 4-methylbenzenesulfonate 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.
