Chemical Structure
Description
2-(4-(5-Acetyl-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidin-4-yl)-2-methoxyphenoxy)acetohydrazide (C16H20N4O5) contains a flavonoid core, 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).
2-(4-(5-Acetyl-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidin-4-yl)-2-methoxyphenoxy)acetohydrazide (CAS 881471-45-0) is a high-purity analytical reference standard with the molecular formula C16H20N4O5 and a molecular weight of 348.35 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.
