Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(R,R)-(-)-1,2-Ethanediylbis[(2-methoxyphenyl)phenylphosphine]rhodium(I) Tetrafluoroborate (CAS 56977-92-5) is a high-purity analytical reference standard with the molecular formula C28H28O2P2C8H12RhBF4 and a molecular weight of 756.37 g/mol.
Structurally, (R,R)-(-)-1,2-Ethanediylbis[(2-methoxyphenyl)phenylphosphine]rhodium(I) Tetrafluoroborate (C28H28O2P2C8H12RhBF4) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 756.37 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
