Chemical Structure
Description
Structurally, (R)-(2'-Ethyl-[1,1'-binaphthalen]-2-yl)diphenylphosphine (C34H27P) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 21.5, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 466.55 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies (R)-(2'-Ethyl-[1,1'-binaphthalen]-2-yl)diphenylphosphine (CAS 137769-32-5), a certified reference material (molecular formula C34H27P, MW 466.55 g/mol) for analytical method development and quality control.
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.
