Chemical Structure
Description
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.
CATO supplies N,N'-[(1R,2R)-1,2-Diphenyl-1,2-ethanediyl]bis[2-diphenylphosphinobenzamide] (CAS 138517-62-1), a certified reference material (molecular formula C52H42N2O2P2, MW 788.85 g/mol) for analytical method development and quality control.
The molecular framework of N,N'-[(1R,2R)-1,2-Diphenyl-1,2-ethanediyl]bis[2-diphenylphosphinobenzamide] (C52H42N2O2P2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
