(2S)-1-[(1S)-1-[Bis(1,1-dimethylethyl)phosphino]ethyl]-2-(diphenylphosphino)ferrocene (acc to CAS) (S)-1-[(RP)-2-(Diphenylphosphino)ferrocenyl]ethyldi-tert-butylphosphine 277306-29-3 Josiphos SL-J002-2 (CAS 277306-29-3), molecular formula C27H47P2C5H5Fe and molecular weight 554.56 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, a polycyclic aromatic system, (2S)-1-[(1S)-1-[Bis(1,1-dimethylethyl)phosphino]ethyl]-2-(diphenylphosphino)ferrocene (acc to CAS) (S)-1-[(RP)-2-(Diphenylphosphino)ferrocenyl]ethyldi-tert-butylphosphine 277306-29-3 Josiphos SL-J002-2 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
