Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxamide (CAS 769-97-1), a certified reference material (molecular formula C5H5N3O3, MW 155.11 g/mol) for analytical method development and quality control.
2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxamide (C5H5N3O3) 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.
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.
