Ethyl 2-(4-fluorophenyl)-5-isopropoxybenzofuran-3-carboxylate CAS 691856-87-8

Description

The occurrence of Ethyl 2-(4-fluorophenyl)-5-isopropoxybenzofuran-3-carboxylate is closely related to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 2-(4-fluorophenyl)-5-isopropoxybenzofuran-3-carboxylate (CAS 691856-87-8) is a high-purity analytical reference standard with the molecular formula C20H19FO4 and a molecular weight of 342.36 g/mol.

Based on its molecular formula C20H19FO4, Ethyl 2-(4-fluorophenyl)-5-isopropoxybenzofuran-3-carboxylate contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 342.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Ethyl 2-(4-fluorophenyl)-5-isopropoxybenzofuran-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
