Chemical Structure
Description
1-[(3-Chlorophenyl)methyl]-2-(2-chloropyridin-3-yl)-5,6-dimethyl-1H-1,3-benzodiazole (C21H17Cl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
