Chemical Structure
Description
Rhodium(II) trifluoroacetate dimer, Rh2(CF3COO)4 31126-95-1 RHODIUM(II) TRIFLUOROACETATE DIMER;TRIFLUOROACETIC ACID RHODIUM(II) SALT DIMER;Rhodium(II) trifluoroacetate dimer, ?Rh2(CF3COO)4 SC10373 (C4F6O4Rh) contains a carbohydrate-derived structure, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Rhodium(II) trifluoroacetate dimer, Rh2(CF3COO)4 31126-95-1 RHODIUM(II) TRIFLUOROACETATE DIMER;TRIFLUOROACETIC ACID RHODIUM(II) SALT DIMER;Rhodium(II) trifluoroacetate dimer, ?Rh2(CF3COO)4 SC10373 (CAS 31126-95-1) is a high-purity analytical reference standard with the molecular formula C4F6O4Rh and a molecular weight of 328.94 g/mol.
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.
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.
