Chemical Structure

2-Ethyl-4-methylfuran-3-carboxylic acid CAS 66505-31-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Ethyl-4-methylfuran-3-carboxylic acid.

CATO supplies 2-Ethyl-4-methylfuran-3-carboxylic acid (CAS 66505-31-5), a certified reference material (molecular formula C8H10O3, MW 154.16 g/mol) for analytical method development and quality control.

The molecular framework of 2-Ethyl-4-methylfuran-3-carboxylic acid (C8H10O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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).

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

As a certified reference material (CRM), 2-Ethyl-4-methylfuran-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.
