Chemical Structure
Description
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.
Dichloro[(R)-(+)-2,2’-bis(diphenylphosphino)-1,1’-binaphthyl]palladium(II) (CAS 115826-95-4), molecular formula C44H32P2Cl2Pd and molecular weight 800.01 g/mol, is a CATO reference standard with documented purity and traceability.
Dichloro[(R)-(+)-2,2’-bis(diphenylphosphino)-1,1’-binaphthyl]palladium(II) (C44H32P2Cl2Pd) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
