Description
As a certified reference material (CRM), 2,4,5-Trichloro-N-{[3-(4-methoxyphenyl)-1,2-oxazol-5-yl]methyl}benzene-1-sulfonamide 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.
2,4,5-Trichloro-N-{[3-(4-methoxyphenyl)-1,2-oxazol-5-yl]methyl}benzene-1-sulfonamide (CAS 339016-97-6) is a high-purity analytical reference standard with the molecular formula C17H13Cl3N2O4S and a molecular weight of 447.72 g/mol.
2,4,5-Trichloro-N-{[3-(4-methoxyphenyl)-1,2-oxazol-5-yl]methyl}benzene-1-sulfonamide (C17H13Cl3N2O4S) contains a flavonoid core, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
