Biurea is a chemical compound with the molecular formula C2H6N4O2. It is produced in food products containing azodicarbonamide, a common ingredient in bread flour, when they are cooked.[2] Upon exposure, biurea is rapidly eliminated from the body through excretion.[3]
Biurea is produced from urea and hydrazine by transamidation. Its major use is as a chemical intermediate in the production of azodicarbonamide, a common blowing agent.[4]
