Sodium 2',4',5',7'-tetrabromo-5-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3-oxo-3H-spiro[isobenzofuran-1,9'-xanthene]-3',6'-bis(olate) CAS 75350-45-7

Description

Structurally, Sodium 2',4',5',7'-tetrabromo-5-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3-oxo-3H-spiro[isobenzofuran-1,9'-xanthene]-3',6'-bis(olate) (C24H9Br4NO7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 742.95 g/mol, it falls into the 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).

Sodium 2',4',5',7'-tetrabromo-5-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3-oxo-3H-spiro[isobenzofuran-1,9'-xanthene]-3',6'-bis(olate) (CAS 75350-45-7) is a high-purity analytical reference standard with the molecular formula C24H9Br4NO7 and a molecular weight of 742.95 g/mol.
