N,N'-[(1R)-5,5',6,6',7,7',8,8'-Octahydro[1,1'-binaphthalene]-2,2'-diyl]bis[P,P-diphenylphosphinous amide] CAS 208248-67-3

Description

N,N'-[(1R)-5,5',6,6',7,7',8,8'-Octahydro[1,1'-binaphthalene]-2,2'-diyl]bis[P,P-diphenylphosphinous amide] (CAS 208248-67-3), molecular formula C44H42N2P2 and molecular weight 660.77 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N,N'-[(1R)-5,5',6,6',7,7',8,8'-Octahydro[1,1'-binaphthalene]-2,2'-diyl]bis[P,P-diphenylphosphinous amide] (C44H42N2P2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 25.0, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 660.77 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.

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.
