Chemical Structure

(S)-N2,N2’-Bis(diphenylphosphino)-[1,1’-binaphthalene]-2,2’-diamine CAS 74974-15-5 chemical structure

Description

(S)-N2,N2’-Bis(diphenylphosphino)-[1,1’-binaphthalene]-2,2’-diamine (CAS 74974-15-5) is a high-purity analytical reference standard with the molecular formula C44H34N2P2 and a molecular weight of 652.70 g/mol.

Based on its molecular formula C44H34N2P2, (S)-N2,N2’-Bis(diphenylphosphino)-[1,1’-binaphthalene]-2,2’-diamine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 652.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
