Ethyl 5-acetoxy-2-methylbenzofuran-3-carboxylate CAS 56820-12-3

Description

Compared with other compounds in its class, the molecular weight of 262.26 g/mol gives Ethyl 5-acetoxy-2-methylbenzofuran-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 5-acetoxy-2-methylbenzofuran-3-carboxylate (CAS 56820-12-3) is a high-purity analytical reference standard with the molecular formula C14H14O5 and a molecular weight of 262.26 g/mol.

The molecular framework of Ethyl 5-acetoxy-2-methylbenzofuran-3-carboxylate (C14H14O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
