6-(4-Fluorophenyl)-3-(piperidin-4-yl)-[1,2,4]triazolo[4,3-b]pyridazine (CAS 1281489-91-5), molecular formula C16H16FN5 and molecular weight 297.33 g/mol, is a CATO reference standard with documented purity and traceability.
6-(4-Fluorophenyl)-3-(piperidin-4-yl)-[1,2,4]triazolo[4,3-b]pyridazine (C16H16FN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
