Chemical Structure
Description
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 supplies 1-Benzyl-6-hydroxy-2-oxo-1,2-dihydropyrimidine-4-carboxylic acid (CAS 338774-89-3), a certified reference material (molecular formula C12H10N2O4, MW 246.22 g/mol) for analytical method development and quality control.
1-Benzyl-6-hydroxy-2-oxo-1,2-dihydropyrimidine-4-carboxylic acid (C12H10N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
