Chemical Structure
Description
(+)-1,1'-BIs((2r,4r)-2,4-diethylphosphotano)ferrocene(1,5-cyclooctadiene)rhodium (i) tetrafluoroborate (CAS 268220-96-8), molecular formula C32H48FeP2RhBF4 and molecular weight 740.24 g/mol, is a CATO reference standard with documented purity and traceability.
(+)-1,1'-BIs((2r,4r)-2,4-diethylphosphotano)ferrocene(1,5-cyclooctadiene)rhodium (i) tetrafluoroborate (C32H48FeP2RhBF4) contains organophosphorus functionality, fluorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
