Chemical Structure

4-Ethoxybenzofuran-2-carboxamide CAS 199287-56-4 chemical structure

Description

The occurrence of 4-Ethoxybenzofuran-2-carboxamide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Ethoxybenzofuran-2-carboxamide (CAS 199287-56-4), a certified reference material (molecular formula C11H11NO3, MW 205.21 g/mol) for analytical method development and quality control.

4-Ethoxybenzofuran-2-carboxamide (C11H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 4-Ethoxybenzofuran-2-carboxamide 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.
