Chemical Structure
Description
The molecular framework of (3E)-3-(2-Oxo-2-phenylethylidene)-2-phenyl-2,3-dihydro-1H-isoindol-1-one (C22H15NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(3E)-3-(2-Oxo-2-phenylethylidene)-2-phenyl-2,3-dihydro-1H-isoindol-1-one (CAS 143647-64-7), molecular formula C22H15NO2 and molecular weight 325.36 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
