Description

The occurrence of (1R)-1-[(1S)-1-[Bis(3,5-bis(trifluoromethyl)phenyl)phosphino]ethyl]-2-[2-(diphenylphosphino)phenyl]ferrocene (acc to CAS) (S)-1-{(SP)-2-[2-(Diphenylphosphino)phenyl]ferrocenyl}ethylbis[3,5-bis-(trifluoromethyl)phenyl]phosphine 849925-17-3 Walphos SL-W001-2 is closely related to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1R)-1-[(1S)-1-[Bis(3,5-bis(trifluoromethyl)phenyl)phosphino]ethyl]-2-[2-(diphenylphosphino)phenyl]ferrocene (acc to CAS) (S)-1-{(SP)-2-[2-(Diphenylphosphino)phenyl]ferrocenyl}ethylbis[3,5-bis-(trifluoromethyl)phenyl]phosphine 849925-17-3 Walphos SL-W001-2 (CAS 849925-17-3), molecular formula C41H57F12P2C5H5Fe and molecular weight 960.77 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (1R)-1-[(1S)-1-[Bis(3,5-bis(trifluoromethyl)phenyl)phosphino]ethyl]-2-[2-(diphenylphosphino)phenyl]ferrocene (acc to CAS) (S)-1-{(SP)-2-[2-(Diphenylphosphino)phenyl]ferrocenyl}ethylbis[3,5-bis-(trifluoromethyl)phenyl]phosphine 849925-17-3 Walphos SL-W001-2 (C41H57F12P2C5H5Fe) contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 960.77 g/mol, it falls into the high-molecular-weight range. 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.
