CATO supplies (E)-1-(5-(Chloromethyl)-1,2,4-oxadiazol-3-yl)-3-(1,3,3-trimethylindolin-2-ylidene)propan-2-one (CAS 885461-53-0), a certified reference material (molecular formula C17H18ClN3O2, MW 331.80 g/mol) for analytical method development and quality control.
The molecular framework of (E)-1-(5-(Chloromethyl)-1,2,4-oxadiazol-3-yl)-3-(1,3,3-trimethylindolin-2-ylidene)propan-2-one (C17H18ClN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (E)-1-(5-(Chloromethyl)-1,2,4-oxadiazol-3-yl)-3-(1,3,3-trimethylindolin-2-ylidene)propan-2-one 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.
