CATO supplies 1-(2-Hydroxyethyl)-2,4,6-triphenylpyridin-1-ium tetrafluoroborate (CAS 1537-40-2), a certified reference material (molecular formula C25H22NOBF4, MW 439.26 g/mol) for analytical method development and quality control.
1-(2-Hydroxyethyl)-2,4,6-triphenylpyridin-1-ium tetrafluoroborate (C25H22NOBF4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
