Chemical Structure
Description
Ethyl (5-Bromo-2-(6-Fluoronicotinoyl)Benzofuran-3-ly)(3-Methoxypropyl)Carbamate (C21H20BrFN2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Ethyl (5-Bromo-2-(6-Fluoronicotinoyl)Benzofuran-3-ly)(3-Methoxypropyl)Carbamate (CAS 1431434-22-8) is a high-purity analytical reference standard with the molecular formula C21H20BrFN2O5 and a molecular weight of 479.30 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
