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 5-Methyl-4-oxo-1,4-dihydropyridine-2-carboxylic acid hydrobromide.
5-Methyl-4-oxo-1,4-dihydropyridine-2-carboxylic acid hydrobromide (CAS 1384430-93-6) is a high-purity analytical reference standard with the molecular formula C7H7NO3HBr and a molecular weight of 234.05 g/mol.
5-Methyl-4-oxo-1,4-dihydropyridine-2-carboxylic acid hydrobromide (C7H7NO3HBr) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 5-Methyl-4-oxo-1,4-dihydropyridine-2-carboxylic acid hydrobromide 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.
