Chemical Structure
Description
(S)-[2’-(2-Methoxybenzyl)-[1,1’-binaphthalen]-2-yl]diphenylphosphine (CAS 1454319-48-2) is a high-purity analytical reference standard with the molecular formula C40H31OP and a molecular weight of 558.65 g/mol.
The molecular framework of (S)-[2’-(2-Methoxybenzyl)-[1,1’-binaphthalen]-2-yl]diphenylphosphine (C40H31OP) is characterized by organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
