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 chloride (CAS 2492-23-1), molecular formula C25H20Cl2PCl and molecular weight 457.76 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C25H20Cl2PCl, (2,4-Dichlorobenzyl)triphenylphosphonium 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 457.76 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.
As a certified reference material (CRM), (2,4-Dichlorobenzyl)triphenylphosphonium chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
