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.
(T-4)-[1,1′-(1,2-Ethanediyl)bis[1,1-diphenylphosphine-κP]]diiodocobalt (CAS 34775-39-8) is a high-purity analytical reference standard with the molecular formula C26H24CoI2P2 and a molecular weight of 711.16 g/mol.
The molecular framework of (T-4)-[1,1′-(1,2-Ethanediyl)bis[1,1-diphenylphosphine-κP]]diiodocobalt (C26H24CoI2P2) is characterized by organophosphorus functionality, iodine substitution, a polycyclic aromatic system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (T-4)-[1,1′-(1,2-Ethanediyl)bis[1,1-diphenylphosphine-κP]]diiodocobalt 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.
