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 methyl 5-bromo-3-cyano-6-methyl-2-oxo-1,2-dihydropyridine-4-carboxylate.
CATO supplies methyl 5-bromo-3-cyano-6-methyl-2-oxo-1,2-dihydropyridine-4-carboxylate (CAS 1630763-53-9), a certified reference material (molecular formula C9H7BrN2O3, MW 271.07 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H7BrN2O3, methyl 5-bromo-3-cyano-6-methyl-2-oxo-1,2-dihydropyridine-4-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
