Description

Compared with other compounds in its class, the molecular weight of 332.01 g/mol gives 3,4-Dichloro-1-(perfluorophenyl)-1H-pyrrole-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Dichloro-1-(perfluorophenyl)-1H-pyrrole-2,5-dione (CAS 186958-58-7), molecular formula C10Cl2F5NO2 and molecular weight 332.01 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,4-Dichloro-1-(perfluorophenyl)-1H-pyrrole-2,5-dione (C10Cl2F5NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 332.01 g/mol, it falls into the moderately-high-molecular-weight range. 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.
