7-Chloro-2-(3-fluorophenyl)-2H-pyrazolo[3,4-d]pyridazine (CAS 1956379-51-3), molecular formula C11H6ClFN4 and molecular weight 248.64 g/mol, is a CATO reference standard with documented purity and traceability.
7-Chloro-2-(3-fluorophenyl)-2H-pyrazolo[3,4-d]pyridazine (C11H6ClFN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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.
