Ethyl 5-bromo-4-fluoro-2-(4-fluorophenyl)benzofuran-3-carboxylate CAS 2420449-27-8

Description

Compared with other compounds in its class, the molecular weight of 381.17 g/mol gives Ethyl 5-bromo-4-fluoro-2-(4-fluorophenyl)benzofuran-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 5-bromo-4-fluoro-2-(4-fluorophenyl)benzofuran-3-carboxylate (CAS 2420449-27-8) is a high-purity analytical reference standard with the molecular formula C17H11BrF2O3 and a molecular weight of 381.17 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine/bromine substitution, Ethyl 5-bromo-4-fluoro-2-(4-fluorophenyl)benzofuran-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
