Chemical Structure
Description
N-(2,4-Dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)-4-methylbenzamide (C12H11N3O3) 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).
N-(2,4-Dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)-4-methylbenzamide (CAS 665025-71-8), molecular formula C12H11N3O3 and molecular weight 245.23 g/mol, is a CATO reference standard with documented purity and traceability.
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.
