(R)-(+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl 23108-72-7 CAS 23108-72-7

Description

Compared with other compounds in its class, the molecular weight of 492.44 g/mol gives (R)-(+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl 23108-72-7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-(+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl 23108-72-7 (CAS 23108-72-7), molecular formula C18H33PCH3Au and molecular weight 492.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (R)-(+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl 23108-72-7 (C18H33PCH3Au) is characterized by organophosphorus functionality. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
