Chemical Structure
Description
Chloro(η5-2,4-cyclopentadien-1-yl)bis[(2-methylphenyl)diphenylphosphine]ruthenium (CAS 252894-17-0), molecular formula C43H39ClP2Ru and molecular weight 754.24 g/mol, is a CATO reference standard with documented purity and traceability.
Chloro(η5-2,4-cyclopentadien-1-yl)bis[(2-methylphenyl)diphenylphosphine]ruthenium (C43H39ClP2Ru) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Chloro(η5-2,4-cyclopentadien-1-yl)bis[(2-methylphenyl)diphenylphosphine]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.
