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.
(SP-4-2)-[1,1′-(1,2-Ethanediyl)bis[1,1-diphenylphosphine-κP]]diiodonickel (CAS 15629-91-1) is a high-purity analytical reference standard with the molecular formula C26H24I2NiP2 and a molecular weight of 710.92 g/mol.
(SP-4-2)-[1,1′-(1,2-Ethanediyl)bis[1,1-diphenylphosphine-κP]]diiodonickel (C26H24I2NiP2) contains organophosphorus functionality, iodine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
