Chemical Structure
Description
The molecular framework of Dichloro(3-methyl-2-butenylidene)bis(triphenylphosphine)ruthenium (C41H38Cl2P2Ru) is characterized by organophosphorus functionality, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Dichloro(3-methyl-2-butenylidene)bis(triphenylphosphine)ruthenium (CAS 191609-95-7), molecular formula C41H38Cl2P2Ru and molecular weight 764.66 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), Dichloro(3-methyl-2-butenylidene)bis(triphenylphosphine)ruthenium 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.
