Chemical Structure

4-(6'-Hydroxy-1',3',4',9a'-tetrahydrospiro[cyclohexane-1,9'-xanthen]-4a'(2'H)-yl)benzene-1,3-diol CAS 138446-23-8 chemical structure

Description

4-(6'-Hydroxy-1',3',4',9a'-tetrahydrospiro[cyclohexane-1,9'-xanthen]-4a'(2'H)-yl)benzene-1,3-diol (C24H28O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

4-(6'-Hydroxy-1',3',4',9a'-tetrahydrospiro[cyclohexane-1,9'-xanthen]-4a'(2'H)-yl)benzene-1,3-diol (CAS 138446-23-8) is a high-purity analytical reference standard with the molecular formula C24H28O4 and a molecular weight of 380.48 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
