Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-(Pentan-2-yl)anthracene-9,10-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.35 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).
2-(Pentan-2-yl)anthracene-9,10-dione (CAS 75931-61-2), molecular formula C19H18O2 and molecular weight 278.35 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
