Description

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.

1-(2,5-Dichlorophenyl)-5-oxopyrrolidine-3-carboxylic acid (CAS 91064-24-3), molecular formula C11H9Cl2NO3 and molecular weight 274.10 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H9Cl2NO3, 1-(2,5-Dichlorophenyl)-5-oxopyrrolidine-3-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.10 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).
