Chemical Structure

1-(2-Chloroethyl)-1H-1,2,4-triazole CAS 3236-66-6 chemical structure

Description

1-(2-Chloroethyl)-1H-1,2,4-triazole (C4H6ClN3) contains a nitrile group, chlorine 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.
