Chemical Structure
Description
Bis(tricyclohexylphosphine)[(phenylthio)methylene]ruthenium(II) dichloride (C7H6Cl2RuSC18H33P) contains sulfur-containing functionality, organophosphorus functionality, chlorine substitution, an aromatic ring 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Bis(tricyclohexylphosphine)[(phenylthio)methylene]ruthenium(II) dichloride (CAS 437767-65-2), molecular formula C7H6Cl2RuSC18H33P and molecular weight 574.59 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
