5-Oxo-1-(2,4,5-trichlorophenyl)pyrrolidine-3-carboxylic acid (CAS 91058-46-7) is a high-purity analytical reference standard with the molecular formula C11H8Cl3NO3 and a molecular weight of 308.55 g/mol.
Structurally, 5-Oxo-1-(2,4,5-trichlorophenyl)pyrrolidine-3-carboxylic acid (C11H8Cl3NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 308.55 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.
