4-(3-Bromo-4-fluorophenyl)-5-chloro-1-ethyl-1H-pyrazolo[3,4-c]pyridazine (CAS 2101298-63-7) is a high-purity analytical reference standard with the molecular formula C13H9BrClFN4 and a molecular weight of 355.59 g/mol.

The molecular framework of 4-(3-Bromo-4-fluorophenyl)-5-chloro-1-ethyl-1H-pyrazolo[3,4-c]pyridazine (C13H9BrClFN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
