Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 502.33 g/mol gives Benzo[d][1,3]dithiol-2-yltriphenylphosphonium tetrafluoroborate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benzo[d][1,3]dithiol-2-yltriphenylphosphonium tetrafluoroborate (CAS 62217-34-9), molecular formula C25H20PS2BF4 and molecular weight 502.33 g/mol, is a CATO reference standard with documented purity and traceability.
Benzo[d][1,3]dithiol-2-yltriphenylphosphonium tetrafluoroborate (C25H20PS2BF4) contains sulfur-containing functionality, 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
