Chemical Structure
Description
3-(Trifluoromethyl)-1,5,6,7-tetrahydro-[1,2,4]triazolo[4,3-a]pyrimidine (C6H7F3N4) contains a nitrile group, fluorine substitution, an aromatic ring system. 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.
