Description

Compared with other compounds in its class, the molecular weight of 735.55 g/mol gives (R,R)-Et-DUPHOS-Rh 1,2-Bis[(2R,5R)-2,5-diethylphospholano]benzene(1,5-cyclooctadiene)rhodium(I) tetrafluoroborate 228121-39-9 [(R,R)Ethyl-DuPhosRh(COD)]BF4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R,R)-Et-DUPHOS-Rh 1,2-Bis[(2R,5R)-2,5-diethylphospholano]benzene(1,5-cyclooctadiene)rhodium(I) tetrafluoroborate 228121-39-9 [(R,R)Ethyl-DuPhosRh(COD)]BF4 (CAS 228121-39-9) is a high-purity analytical reference standard with the molecular formula C24H44P2RhC8H12BF3C3H7F and a molecular weight of 735.55 g/mol.

The molecular framework of (R,R)-Et-DUPHOS-Rh 1,2-Bis[(2R,5R)-2,5-diethylphospholano]benzene(1,5-cyclooctadiene)rhodium(I) tetrafluoroborate 228121-39-9 [(R,R)Ethyl-DuPhosRh(COD)]BF4 (C24H44P2RhC8H12BF3C3H7F) is characterized by organophosphorus functionality, 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. 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.
