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 (<I> S </I>)-1-[(<I> R </I> <SUB> P </SUB>)-2-(dicyclohexylphosphine)ferrocene]ethyldi- <I>tert-butylphosphine</I> (CAS 1246841-00-8), a certified reference material (molecular formula C27H47P2C5H5Fe, MW 554.56 g/mol) for analytical method development and quality control.
(<I> S </I>)-1-[(<I> R </I> <SUB> P </SUB>)-2-(dicyclohexylphosphine)ferrocene]ethyldi- <I>tert-butylphosphine</I> (C27H47P2C5H5Fe) contains organophosphorus functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
