Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,4-Dioxo-1,2,3,4-tetrahydropyrimidine-5-sulfonyl fluoride (CAS 53489-92-2), molecular formula C4H3FN2O4S and molecular weight 194.14 g/mol, is a CATO reference standard with documented purity and traceability.
2,4-Dioxo-1,2,3,4-tetrahydropyrimidine-5-sulfonyl fluoride (C4H3FN2O4S) contains a carbohydrate-derived structure, an amide group, a sulfone group, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), 2,4-Dioxo-1,2,3,4-tetrahydropyrimidine-5-sulfonyl fluoride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
