Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 430.46 g/mol gives (R)-2,2-diphenyl-2-(pyrrolidin-3-yl)acetamide 2,3-dihydroxysuccinate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-2,2-diphenyl-2-(pyrrolidin-3-yl)acetamide 2,3-dihydroxysuccinate (CAS 1092540-94-7), molecular formula C18H20N2OC4H6O6 and molecular weight 430.46 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-2,2-diphenyl-2-(pyrrolidin-3-yl)acetamide 2,3-dihydroxysuccinate (C18H20N2OC4H6O6) 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.
