Chemical Structure

2,5-Dimethylfuran CAS 625-86-5 chemical structure

Description

2,5-Dimethylfuran (CAS 625-86-5) is a high-purity analytical reference standard with the molecular formula C6H8O and a molecular weight of 96.13 g/mol.

Owing to a hydroxyl group, an ether linkage, 2,5-Dimethylfuran is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 96.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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