2-((2-Oxocyclopentyl)(phenyl)methyl)-3,4-dihydronaphthalen-1(2H)-one (CAS 65419-98-9), molecular formula C22H22O2 and molecular weight 318.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-((2-Oxocyclopentyl)(phenyl)methyl)-3,4-dihydronaphthalen-1(2H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.41 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
