Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-{[N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)4-fluorobenzenesulfonamido]methyl}-N-[(phenylcarbamoyl)amino]-4,5-dihydro-1,2-oxazole-3-carboxamide.
5-{[N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)4-fluorobenzenesulfonamido]methyl}-N-[(phenylcarbamoyl)amino]-4,5-dihydro-1,2-oxazole-3-carboxamide (CAS 338961-99-2) is a high-purity analytical reference standard with the molecular formula C26H24ClF4N7O5S and a molecular weight of 658.02 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 5-{[N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)4-fluorobenzenesulfonamido]methyl}-N-[(phenylcarbamoyl)amino]-4,5-dihydro-1,2-oxazole-3-carboxamide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 658.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 5-{[N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)4-fluorobenzenesulfonamido]methyl}-N-[(phenylcarbamoyl)amino]-4,5-dihydro-1,2-oxazole-3-carboxamide 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.
