Description
As a certified reference material (CRM), cis-Dibromobis(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.
cis-Dibromobis(triphenylphosphine)palladium (CAS 25044-96-6) is a high-purity analytical reference standard with the molecular formula Br2PdC18H15P and a molecular weight of 528.52 g/mol.
The molecular framework of cis-Dibromobis(triphenylphosphine)palladium (Br2PdC18H15P) is characterized by organophosphorus functionality, bromine substitution, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
