4,5-Dimethylene-1,3-dioxolan-2-one CAS 62458-20-2

Description

Compared with other compounds in its class, the molecular weight of 112.08 g/mol gives 4,5-Dimethylene-1,3-dioxolan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,5-Dimethylene-1,3-dioxolan-2-one (CAS 62458-20-2), molecular formula C5H4O3 and molecular weight 112.08 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4,5-Dimethylene-1,3-dioxolan-2-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.08 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.
