Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2,4-Dichlorobenzyl)triphenylphosphonium iodide (CAS 73790-38-2), molecular formula C25H20Cl2PI and molecular weight 549.21 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C25H20Cl2PI, (2,4-Dichlorobenzyl)triphenylphosphonium iodide contains organophosphorus functionality, chlorine/iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 549.21 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.
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.
