Chemical Structure
Description
Based on its molecular formula C25H22PF6Sb, benzyltriphenylphosphoniumHexafluoroantimonate contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 589.17 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.
benzyltriphenylphosphoniumHexafluoroantimonate (CAS 84549-97-3), molecular formula C25H22PF6Sb and molecular weight 589.17 g/mol, is a CATO reference standard with documented purity and traceability.
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), benzyltriphenylphosphoniumHexafluoroantimonate 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.
