Chemical Structure

(11bR)-N-[(1R)-1-[2-(Diphenylphosphino)phenyl]ethyl]-8,9,10,11,12,13,14,15-octahydro-N-methyldinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine CAS 1332500-22-7 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.

(11bR)-N-[(1R)-1-[2-(Diphenylphosphino)phenyl]ethyl]-8,9,10,11,12,13,14,15-octahydro-N-methyldinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine (CAS 1332500-22-7) is a high-purity analytical reference standard with the molecular formula C41H41NO2P2 and a molecular weight of 641.72 g/mol.

The molecular framework of (11bR)-N-[(1R)-1-[2-(Diphenylphosphino)phenyl]ethyl]-8,9,10,11,12,13,14,15-octahydro-N-methyldinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine (C41H41NO2P2) 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.

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.
