Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Triphenyl(3,3,3-trichloropropyl)phosphonium chloride (CAS 804482-50-6), molecular formula C21H19Cl3PCl and molecular weight 444.16 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H19Cl3PCl, Triphenyl(3,3,3-trichloropropyl)phosphonium chloride contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 444.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
