Chemical Structure
Description
The occurrence of Potassium 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate (CAS 24598-73-0) is a high-purity analytical reference standard with the molecular formula C5H5N2O4K and a molecular weight of 196.20 g/mol.
Potassium 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate (C5H5N2O4K) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
