Chemical Structure
Description
2-(2,4-Dichlorophenyl)-4-(1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene)-6-(pyridin-2-yl)-octahydropyrrolo[3,4-c]pyrrole-1,3-dione (C26H15Cl2N3O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-(2,4-Dichlorophenyl)-4-(1,3-dioxo-2,3-dihydro-1H-inden-2-ylidene)-6-(pyridin-2-yl)-octahydropyrrolo[3,4-c]pyrrole-1,3-dione (CAS 321392-08-9), molecular formula C26H15Cl2N3O4 and molecular weight 504.32 g/mol, is a CATO reference standard with documented purity and traceability.
