Chemical Structure
Description
The molecular framework of 2-{2-[4-(2,3-dihydro-1H-inden-5-yl)-1-oxo-1,2-dihydrophthalazin-2-yl]ethyl}-2,3-dihydro-1H-isoindole-1,3-dione (C27H21N3O3) 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 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).
2-{2-[4-(2,3-dihydro-1H-inden-5-yl)-1-oxo-1,2-dihydrophthalazin-2-yl]ethyl}-2,3-dihydro-1H-isoindole-1,3-dione (CAS 866132-95-8) is a high-purity analytical reference standard with the molecular formula C27H21N3O3 and a molecular weight of 435.47 g/mol.
