Dichloro [(R)-(+)-2,2-bis(diphenylphosphino)-1,1-binaphathyl] ruthenium(II) CAS 132071-87-5

Description

The occurrence of Dichloro [(R)-(+)-2,2-bis(diphenylphosphino)-1,1-binaphathyl] ruthenium(II) is closely related to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dichloro [(R)-(+)-2,2-bis(diphenylphosphino)-1,1-binaphathyl] ruthenium(II) (CAS 132071-87-5), molecular formula C44H32Cl2P2Ru and molecular weight 794.65 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dichloro [(R)-(+)-2,2-bis(diphenylphosphino)-1,1-binaphathyl] ruthenium(II) (C44H32Cl2P2Ru) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 794.65 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.

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.
