Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Dipotassium Anthraquinone-1,8-disulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.41 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).
Dipotassium Anthraquinone-1,8-disulfonate (CAS 14938-42-2) is a high-purity analytical reference standard with the molecular formula C14H6O8S2K and a molecular weight of 405.41 g/mol.
