Description
As a certified reference material (CRM), (4-Chlorobenzyl)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.
(4-Chlorobenzyl)triphenylphosphonium Chloride (CAS 1530-39-8) is a high-purity analytical reference standard with the molecular formula C25H21ClPCl and a molecular weight of 423.32 g/mol.
(4-Chlorobenzyl)triphenylphosphonium Chloride (C25H21ClPCl) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
