The molecular framework of (3e)-4-[(1s,4as,8as)-5,5,8a-trimethyl-2-methylenedecahydro-1-naph Thalenyl]-3-buten-2-one 76497-69-3 (C18H28O) is characterized by a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
