Chemical Structure

N-Ethyl-5-hydroxy-1,2-dimethyl-6-oxo-1,6-dihydropyrimidine-4-carboxamide CAS 389130-73-8 chemical structure

Description

The occurrence of N-Ethyl-5-hydroxy-1,2-dimethyl-6-oxo-1,6-dihydropyrimidine-4-carboxamide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-Ethyl-5-hydroxy-1,2-dimethyl-6-oxo-1,6-dihydropyrimidine-4-carboxamide (CAS 389130-73-8), a certified reference material (molecular formula C9H13N3O3, MW 211.22 g/mol) for analytical method development and quality control.

N-Ethyl-5-hydroxy-1,2-dimethyl-6-oxo-1,6-dihydropyrimidine-4-carboxamide (C9H13N3O3) 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).

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.
