Chemical Structure

2,5-Dihydrofuran-2-carboxylic acid CAS 22694-55-9 chemical structure

Description

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 supplies 2,5-Dihydrofuran-2-carboxylic acid (CAS 22694-55-9), a certified reference material (molecular formula C5H6O3, MW 114.10 g/mol) for analytical method development and quality control.

Structurally, 2,5-Dihydrofuran-2-carboxylic acid (C5H6O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 114.10 g/mol, it falls into the low-molecular-weight range. 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).

As a certified reference material (CRM), 2,5-Dihydrofuran-2-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.
