4-(1,1-Diethoxyethyl)-2-thioxo-1,2-dihydropyrimidine-5-carboxylic acid CAS 62328-11-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(1,1-Diethoxyethyl)-2-thioxo-1,2-dihydropyrimidine-5-carboxylic acid.

4-(1,1-Diethoxyethyl)-2-thioxo-1,2-dihydropyrimidine-5-carboxylic acid (CAS 62328-11-4) is a high-purity analytical reference standard with the molecular formula C11H16N2O4S and a molecular weight of 272.32 g/mol.

4-(1,1-Diethoxyethyl)-2-thioxo-1,2-dihydropyrimidine-5-carboxylic acid (C11H16N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
