Chemical Structure
Description
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.
Chromium, triiodo[tris[2-(diphenylphosphino)ethyl]phosphine]- (CAS 89655-19-6) is a high-purity analytical reference standard with the molecular formula C42H42CrI3P4 and a molecular weight of 1103.39 g/mol.
Based on its molecular formula C42H42CrI3P4, Chromium, triiodo[tris[2-(diphenylphosphino)ethyl]phosphine]- contains organophosphorus functionality, iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1103.39 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.
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.
