(1S)-1-[Bis(1,1-dimethylethyl)phosphino]-2-[(1S)-1-(diphenylphosphino)ethyl]ferrocene (acc to CAS) (S)-1-[(RP)-2-(Di-tert-butylphosphino)ferrocenyl]ethyldiphenylphosphine 223121-01-5 Josiphos SL-J502-2 CAS 223121-01-5

Description

Owing to organophosphorus functionality, a polycyclic aromatic system, (1S)-1-[Bis(1,1-dimethylethyl)phosphino]-2-[(1S)-1-(diphenylphosphino)ethyl]ferrocene (acc to CAS) (S)-1-[(RP)-2-(Di-tert-butylphosphino)ferrocenyl]ethyldiphenylphosphine 223121-01-5 Josiphos SL-J502-2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 554.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(1S)-1-[Bis(1,1-dimethylethyl)phosphino]-2-[(1S)-1-(diphenylphosphino)ethyl]ferrocene (acc to CAS) (S)-1-[(RP)-2-(Di-tert-butylphosphino)ferrocenyl]ethyldiphenylphosphine 223121-01-5 Josiphos SL-J502-2 (CAS 223121-01-5) is a high-purity analytical reference standard with the molecular formula C27H47P2C5H5Fe and a molecular weight of 554.56 g/mol.

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.
