Chemical Structure
Description
3,3,7-Trimethyl-3H-furo[2,3-b]pyrano[3,2-f]quinolin-11(7H)-one (CAS 35307-24-5) is a high-purity analytical reference standard with the molecular formula C17H15NO3 and a molecular weight of 281.31 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3,3,7-Trimethyl-3H-furo[2,3-b]pyrano[3,2-f]quinolin-11(7H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.31 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
