Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 385.28 g/mol gives Triphenyl(propyl)phosphonium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Triphenyl(propyl)phosphonium (CAS 15912-75-1), a certified reference material (molecular formula C21H22PBr, MW 385.28 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H22PBr, Triphenyl(propyl)phosphonium contains organophosphorus functionality, bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 385.28 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.
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), Triphenyl(propyl)phosphonium 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.
