Description

Structurally, 143724-76-9 3,4',5,7-Tetrahydroxy-8-(3-methyl-2-butenyl)flavone Tri-O-methoxymethyl Ether 3,5,7-Trihydroxy-2-(4-hydroxyphenyl)-8-(3-methyl-2-buten-1-yl)-4H-1-benzopyran-4-one 4'-Desmethylicaritin Tri-O-methoxymethyl Ether 8-Prenylkaempferol Tri-O-methoxymethyl Ether De-O-methylanhydroicaritin Tri-O-methoxymethyl Ether Desmethyl Icaritin Tri-O-methoxymethyl Ether Noranhydroicaritin Tri-O-methoxymethyl Ether (C26H30O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 486.51 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
