Chemical Structure
Description
4-{[(5-Oxo-1-phenylpyrrolidin-3-yl)carbonyl]-amino}benzoic acid (CAS 401822-11-5) is a high-purity analytical reference standard with the molecular formula C18H16N2O4 and a molecular weight of 324.33 g/mol.
4-{[(5-Oxo-1-phenylpyrrolidin-3-yl)carbonyl]-amino}benzoic acid (C18H16N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
