Chemical Structure
Description
The occurrence of 2,2',6,6'-Tetraphenyl-[4,4'-bithiopyran]-1,1'-diium tetrafluoroborate is closely related to sulfur-containing functionality, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,2',6,6'-Tetraphenyl-[4,4'-bithiopyran]-1,1'-diium tetrafluoroborate (CAS 42559-33-1), a certified reference material (molecular formula C34H24S2BF4, MW 583.49 g/mol) for analytical method development and quality control.
2,2',6,6'-Tetraphenyl-[4,4'-bithiopyran]-1,1'-diium tetrafluoroborate (C34H24S2BF4) contains sulfur-containing 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 2,2',6,6'-Tetraphenyl-[4,4'-bithiopyran]-1,1'-diium tetrafluoroborate 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.
