Chemical Structure
Description
2-((2,6-Dichlorobenzyl)thio)-7-(pyridin-2-yl)-[1,2,4]triazolo[1,5-a]pyrimidine (C17H11Cl2N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
