Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1-(4,7-Diethoxy-6-hydroxybenzofuran-5-yl)ethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1-(4,7-Diethoxy-6-hydroxybenzofuran-5-yl)ethanone (CAS 88349-53-5), molecular formula C14H16O5 and molecular weight 264.27 g/mol, is a CATO reference standard with documented purity and traceability.
