Chemical Structure
Description
The molecular framework of 6-Chloro-3-(thiophen-2-yl)-[1,2,4]triazolo[4,3-b]pyridazine (C9H5ClN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
