N-(5-(4-Bromophenyl)-1,3,4-oxadiazol-2-yl)-2,2-diphenylacetamide (CAS 897735-69-2), molecular formula C22H16BrN3O2 and molecular weight 434.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(5-(4-Bromophenyl)-1,3,4-oxadiazol-2-yl)-2,2-diphenylacetamide (C22H16BrN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures N-(5-(4-Bromophenyl)-1,3,4-oxadiazol-2-yl)-2,2-diphenylacetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
