Chemical Structure

3,6-Dihydro-2h-pyran-2,6-dione CAS 5926-95-4 chemical structure

Description

The molecular framework of 3,6-Dihydro-2h-pyran-2,6-dione (C5H4O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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).

3,6-Dihydro-2h-pyran-2,6-dione (CAS 5926-95-4) is a high-purity analytical reference standard with the molecular formula C5H4O3 and a molecular weight of 112.08 g/mol.

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.
