Chemical Structure

2-ethylbenzofuran-3-carboxylic acid CAS 52489-34-6 chemical structure

Description

As a certified reference material (CRM), 2-ethylbenzofuran-3-carboxylic acid 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.

2-ethylbenzofuran-3-carboxylic acid (CAS 52489-34-6) is a high-purity analytical reference standard with the molecular formula C11H18O3 and a molecular weight of 198.26 g/mol.

The molecular framework of 2-ethylbenzofuran-3-carboxylic acid (C11H18O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
