Chemical Structure
Description
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.
(E)-3-(6-fluoro-4-hydroxy-2-methylquinolin-3-yl)-n-(4-fluorophenyl)but-2-enamide (CAS 1150271-29-6) is a high-purity analytical reference standard with the molecular formula C20H16F2N2O2 and a molecular weight of 354.35 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (E)-3-(6-fluoro-4-hydroxy-2-methylquinolin-3-yl)-n-(4-fluorophenyl)but-2-enamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
