56617-66-4 WK38ZDT69B Demethoxyviridiol Cyclopenta(7,8)phenanthro(10,1-bc)furan-6,9-dione, 1,2,3,7,8,11b-hexahydro-1,3-dihydroxy-11b-methyl-, (1R-(1-alpha,3-alpha,11b-alpha))- Desmethoxyviridiol UNII-WK38ZDT69B (CAS 56617-66-4) is a high-purity analytical reference standard with the molecular formula C19H16O5 and a molecular weight of 324.33 g/mol.
Structurally, 56617-66-4 WK38ZDT69B Demethoxyviridiol Cyclopenta(7,8)phenanthro(10,1-bc)furan-6,9-dione, 1,2,3,7,8,11b-hexahydro-1,3-dihydroxy-11b-methyl-, (1R-(1-alpha,3-alpha,11b-alpha))- Desmethoxyviridiol UNII-WK38ZDT69B (C19H16O5) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 324.33 g/mol, it falls into the moderately-high-molecular-weight range. 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).
