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]
