Compared with other compounds in its class, the molecular weight of 152.96 g/mol gives 3,4-Dichloro-2,5-dihydrofuran-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,4-Dichloro-2,5-dihydrofuran-2-one (CAS 62674-12-8) is a high-purity analytical reference standard with the molecular formula C4H2Cl2O2 and a molecular weight of 152.96 g/mol.
The molecular framework of 3,4-Dichloro-2,5-dihydrofuran-2-one (C4H2Cl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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.
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.
