2,5-Diethylfuran-3-carboxylic acid CAS 758723-72-7

Description

The occurrence of 2,5-Diethylfuran-3-carboxylic acid 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.

2,5-Diethylfuran-3-carboxylic acid (CAS 758723-72-7), molecular formula C9H12O3 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,5-Diethylfuran-3-carboxylic acid (C9H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 168.19 g/mol, it falls into the medium-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).

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

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.
