Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Triphenyloxonium tetrafluoroborate (CAS 1581-55-1), a certified reference material (molecular formula C18H15OBF4, MW 334.12 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution, Triphenyloxonium tetrafluoroborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Triphenyloxonium 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.
