4,5-Diethylfuran-2-carboxylic acid CAS 84521-65-3

Description

Compared with other compounds in its class, the molecular weight of 168.19 g/mol gives 4,5-Diethylfuran-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,5-Diethylfuran-2-carboxylic acid (CAS 84521-65-3) is a high-purity analytical reference standard with the molecular formula C9H12O3 and a molecular weight of 168.19 g/mol.

The molecular framework of 4,5-Diethylfuran-2-carboxylic acid (C9H12O3) 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).

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.
