Rhodium(1+), [(1,2,5,6-η)-1,5-cyclooctadiene][(2R,2'R,5R,5'R)-1,1'-(1,2-ethanediyl)bis[2,5-dimethylphospholane-κP]]-, salt with trifluoroacetic acid (CAS 171597-48-1), molecular formula C22H40P2RhC2F3O2 and molecular weight 582.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Rhodium(1+), [(1,2,5,6-η)-1,5-cyclooctadiene][(2R,2'R,5R,5'R)-1,1'-(1,2-ethanediyl)bis[2,5-dimethylphospholane-κP]]-, salt with trifluoroacetic acid (C22H40P2RhC2F3O2) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
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.
