• A stable 1:1 complex with hydrazine has been isolated and found to be a useful, safer replacement for anhydrous hydrazine, e.g. in the solid state reaction with esters to give hydrazides: J. Chem. Soc.,Chem. Commun., 1531 (1995).
• Widely used as a radical trap to inhibit polymerization and peroxidation reactions.
