Chemical Structure
Description
The occurrence of Benzyltriphenylphosphonium tetrafluoroborate is closely related to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Benzyltriphenylphosphonium tetrafluoroborate (CAS 31240-52-5), a certified reference material (molecular formula C25H22PBF4, MW 440.23 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system, Benzyltriphenylphosphonium tetrafluoroborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 440.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Benzyltriphenylphosphonium tetrafluoroborate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
