Chemical Structure
Description
(2S,4S)-1-((Benzyloxy)carbonyl)-4-(((benzyloxy)carbonyl)amino)pyrrolidine-2-carboxylic acid (CAS 29475-98-7), molecular formula C21H22N2O6 and molecular weight 398.41 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H22N2O6, (2S,4S)-1-((Benzyloxy)carbonyl)-4-(((benzyloxy)carbonyl)amino)pyrrolidine-2-carboxylic acid contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 398.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
