CATO supplies 1-Ethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (CAS 57712-57-9), a certified reference material (molecular formula C7H7N3O2, MW 165.15 g/mol) for analytical method development and quality control.
1-Ethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (C7H7N3O2) 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).
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.
