Chemical Structure
Description
{(S,S)-N,N′-Bis[2-(diphenylphosphino)benzylidene]cyclohexane-1,2-diamine}dichlororuthenium(II) (CAS 208945-41-9), molecular formula C44H40Cl2N2P2Ru and molecular weight 830.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of {(S,S)-N,N′-Bis[2-(diphenylphosphino)benzylidene]cyclohexane-1,2-diamine}dichlororuthenium(II) (C44H40Cl2N2P2Ru) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), {(S,S)-N,N′-Bis[2-(diphenylphosphino)benzylidene]cyclohexane-1,2-diamine}dichlororuthenium(II) 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.
