Chemical Structure
Description
(4-Iodobutyl)triphenylphosphanium iodide (CAS 159085-21-9), molecular formula C22H23IPI and molecular weight 572.20 g/mol, is a CATO reference standard with documented purity and traceability.
(4-Iodobutyl)triphenylphosphanium iodide (C22H23IPI) contains organophosphorus functionality, iodine 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.
As a certified reference material (CRM), (4-Iodobutyl)triphenylphosphanium iodide 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.
