[1,1'-[(Methylsilylene-κH,κSi)di-2,1-phenylene]bis[1,1-diphenylphosphine-κP]](triphenylphosphine)palladium (CAS 1198806-66-4), molecular formula C55H47P3PdSi and molecular weight 935.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of [1,1'-[(Methylsilylene-κH,κSi)di-2,1-phenylene]bis[1,1-diphenylphosphine-κP]](triphenylphosphine)palladium (C55H47P3PdSi) is characterized by organophosphorus functionality, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), [1,1'-[(Methylsilylene-κH,κSi)di-2,1-phenylene]bis[1,1-diphenylphosphine-κP]](triphenylphosphine)palladium 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.
