2,3-Diphenyl-5-(2-thienyl)tetrazolium Chloride (CAS 38800-20-3), molecular formula C17H15N4SCl and molecular weight 342.84 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Diphenyl-5-(2-thienyl)tetrazolium Chloride (C17H15N4SCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
