9,10-Dimethoxy-1,2,3,4,5,6,7,8-octamethylanthracene (CAS 75670-41-6), molecular formula C24H30O2 and molecular weight 350.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 9,10-Dimethoxy-1,2,3,4,5,6,7,8-octamethylanthracene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.49 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
