(1R)-1-[Bis(1,1-dimethylethyl)phosphino]-2-[(1R)-1-[bis(2-methylphenyl)phosphino]ethyl]ferrocene (acc to CAS) (R)-1-[(SP)-2-(Di-tert-butylphosphino)ferrocenyl]ethylbis(2-methylphenyl)phosphine 849924-76-1 Josiphos SL-J505-1 (CAS 849924-76-1) is a high-purity analytical reference standard with the molecular formula C29H51P2C5H5Fe and a molecular weight of 582.62 g/mol.
Structurally, (1R)-1-[Bis(1,1-dimethylethyl)phosphino]-2-[(1R)-1-[bis(2-methylphenyl)phosphino]ethyl]ferrocene (acc to CAS) (R)-1-[(SP)-2-(Di-tert-butylphosphino)ferrocenyl]ethylbis(2-methylphenyl)phosphine 849924-76-1 Josiphos SL-J505-1 (C29H51P2C5H5Fe) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 582.62 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (1R)-1-[Bis(1,1-dimethylethyl)phosphino]-2-[(1R)-1-[bis(2-methylphenyl)phosphino]ethyl]ferrocene (acc to CAS) (R)-1-[(SP)-2-(Di-tert-butylphosphino)ferrocenyl]ethylbis(2-methylphenyl)phosphine 849924-76-1 Josiphos SL-J505-1 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
