Chemical Structure
Description
The occurrence of Tri-o-tolylphosphine 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 Tri-o-tolylphosphine tetrafluoroborate (CAS 1255640-57-3), a certified reference material (molecular formula C21H22PBF4, MW 392.18 g/mol) for analytical method development and quality control.
Tri-o-tolylphosphine tetrafluoroborate (C21H22PBF4) contains organophosphorus functionality, fluorine 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.
CATO manufactures Tri-o-tolylphosphine 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.
