CATO supplies 5-({[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}methyl)-N-[(1E)-{[(2,4-dichlorophenyl)methoxy]amino}methylidene]-4,5-dihydro-1,2-oxazole-3-carboxamide (CAS 338399-37-4), a certified reference material (molecular formula C19H15Cl3F3N5O3, MW 524.71 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 5-({[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}methyl)-N-[(1E)-{[(2,4-dichlorophenyl)methoxy]amino}methylidene]-4,5-dihydro-1,2-oxazole-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 524.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 5-({[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}methyl)-N-[(1E)-{[(2,4-dichlorophenyl)methoxy]amino}methylidene]-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.
