3-Methoxyfuran-2,5-dione CAS 69945-03-5

Description

The occurrence of 3-Methoxyfuran-2,5-dione is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Methoxyfuran-2,5-dione (CAS 69945-03-5) is a high-purity analytical reference standard with the molecular formula C5H4O4 and a molecular weight of 128.08 g/mol.

Based on its molecular formula C5H4O4, 3-Methoxyfuran-2,5-dione contains a carbohydrate-derived structure; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 128.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
