Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-((6-Chloropyrimidin-4-yl)oxy)benzenesulfonamide (CAS 1242240-93-2), molecular formula C10H8ClN3O3S and molecular weight 285.71 g/mol, is a CATO reference standard with documented purity and traceability.
4-((6-Chloropyrimidin-4-yl)oxy)benzenesulfonamide (C10H8ClN3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4-((6-Chloropyrimidin-4-yl)oxy)benzenesulfonamide 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.
