5,7,3,4,5-pentahydroxy-3-methoxyflavone (CAS 1486-67-5) is a high-purity analytical reference standard with the molecular formula C16H12O8 and a molecular weight of 332.26 g/mol.
Structurally, 5,7,3,4,5-pentahydroxy-3-methoxyflavone (C16H12O8) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 332.26 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
