Chemical Structure
Description
(2S,4R)-4-(tert-Butoxy)-1-(((2-(3,5-dimethoxyphenyl)propan-2-yl)oxy)carbonyl)pyrrolidine-2-carboxylic acid (CAS 79775-05-6) is a high-purity analytical reference standard with the molecular formula C21H31NO7 and a molecular weight of 409.47 g/mol.
(2S,4R)-4-(tert-Butoxy)-1-(((2-(3,5-dimethoxyphenyl)propan-2-yl)oxy)carbonyl)pyrrolidine-2-carboxylic acid (C21H31NO7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
