Chemical Structure
Description
The occurrence of (R)-N2,N2’-Bis(diphenylphosphino)-[1,1’-binaphthalene]-2,2’-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-N2,N2’-Bis(diphenylphosphino)-[1,1’-binaphthalene]-2,2’-diamine (CAS 74974-14-4), molecular formula C44H34N2P2 and molecular weight 652.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, (R)-N2,N2’-Bis(diphenylphosphino)-[1,1’-binaphthalene]-2,2’-diamine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 652.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), (R)-N2,N2’-Bis(diphenylphosphino)-[1,1’-binaphthalene]-2,2’-diamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
