CATO supplies (E)-N-(2-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)amino)ethyl)-4-fluoro-N-((3-(2-(4-fluorobenzylidene)hydrazine-1-carbonyl)-4,5-dihydroisoxazol-5-yl)methyl)benzenesulfonamide (CAS 338961-96-9), a certified reference material (molecular formula C26H22ClF5N6O4S, MW 645.00 g/mol) for analytical method development and quality control.
Structurally, (E)-N-(2-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)amino)ethyl)-4-fluoro-N-((3-(2-(4-fluorobenzylidene)hydrazine-1-carbonyl)-4,5-dihydroisoxazol-5-yl)methyl)benzenesulfonamide (C26H22ClF5N6O4S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 645.00 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (E)-N-(2-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)amino)ethyl)-4-fluoro-N-((3-(2-(4-fluorobenzylidene)hydrazine-1-carbonyl)-4,5-dihydroisoxazol-5-yl)methyl)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.
