Chemical Structure
Description
3-(2-Imino-4-methyl-6-oxo-3,6-dihydropyrimidin-1(2h)-yl)propanoic acid (C8H11N3O3) 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).
3-(2-Imino-4-methyl-6-oxo-3,6-dihydropyrimidin-1(2h)-yl)propanoic acid (CAS 19675-50-4) is a high-purity analytical reference standard with the molecular formula C8H11N3O3 and a molecular weight of 197.19 g/mol.
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.
