The occurrence of Methyldiphenyl(prop-1-en-2-yl)phosphonium iodide is closely related to organophosphorus functionality, iodine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyldiphenyl(prop-1-en-2-yl)phosphonium iodide (CAS 30670-21-4), molecular formula C16H18PI and molecular weight 368.19 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H18PI, Methyldiphenyl(prop-1-en-2-yl)phosphonium iodide contains organophosphorus functionality, iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.19 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.
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.
