Chemical Structure

Ethyl 4-hydroxy-2-oxo-2,5-dihydro-3-furancarboxylate CAS 21053-90-7 chemical structure

Description

The occurrence of Ethyl 4-hydroxy-2-oxo-2,5-dihydro-3-furancarboxylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 4-hydroxy-2-oxo-2,5-dihydro-3-furancarboxylate (CAS 21053-90-7), a certified reference material (molecular formula C7H8O5, MW 172.14 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 4-hydroxy-2-oxo-2,5-dihydro-3-furancarboxylate (C7H8O5) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures Ethyl 4-hydroxy-2-oxo-2,5-dihydro-3-furancarboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
