Chemical Structure
Description
6-Cyclohexyl-4-hydroxy-2H-pyrano[3,2-c]quinoline-2,5(6H)-dione (CAS 866149-95-3) is a high-purity analytical reference standard with the molecular formula C18H17NO4 and a molecular weight of 311.33 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 6-Cyclohexyl-4-hydroxy-2H-pyrano[3,2-c]quinoline-2,5(6H)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.33 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.
