Chemical Structure
Description
As a certified reference material (CRM), Ethyltriphenylphosphonium 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.
Ethyltriphenylphosphonium Chloride (CAS 896-33-3), molecular formula C20H20PCl and molecular weight 326.80 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyltriphenylphosphonium Chloride (C20H20PCl) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
