Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dimethoxy-9-[2-(trifluoromethyl)phenyl]-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one.
CATO supplies 6,7-Dimethoxy-9-[2-(trifluoromethyl)phenyl]-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one (CAS 900014-91-7), a certified reference material (molecular formula C20H16F3NO4, MW 391.34 g/mol) for analytical method development and quality control.
Structurally, 6,7-Dimethoxy-9-[2-(trifluoromethyl)phenyl]-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one (C20H16F3NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 391.34 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
