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-Bromo-1-(2-(tert-butoxy)-2-oxoethyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid.
CATO supplies 5-Bromo-1-(2-(tert-butoxy)-2-oxoethyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (CAS 2138236-26-5), a certified reference material (molecular formula C12H14BrNO5, MW 332.15 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H14BrNO5, 5-Bromo-1-(2-(tert-butoxy)-2-oxoethyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid 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 332.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
