Chemical Structure
Description
The molecular framework of (4R,4'R)-2,2'-(1,3-Dihydro-2H-inden-2-ylidene)bis[4,5-dihydro-4-isopropyloxazole] (C21H28N2O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
