2,4-Dioxo-1-(pyridin-4-ylmethyl)-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (CAS 341966-23-2), molecular formula C11H8N4O2 and molecular weight 228.21 g/mol, is a CATO reference standard with documented purity and traceability.
2,4-Dioxo-1-(pyridin-4-ylmethyl)-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (C11H8N4O2) 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. 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.
