Chemical Structure
Description
(2S,2’S)-1,1’-[(2-Hydroxy-5-methyl-1,3-phenylene)bis(methylene)]bis[alpha,alpha-diphenyl-2-pyrrolidinemethanol] (CAS 320714-00-9) is a high-purity analytical reference standard with the molecular formula C43H46N2O3 and a molecular weight of 638.84 g/mol.
The molecular framework of (2S,2’S)-1,1’-[(2-Hydroxy-5-methyl-1,3-phenylene)bis(methylene)]bis[alpha,alpha-diphenyl-2-pyrrolidinemethanol] (C43H46N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
