Azodicarbonamide 123-77-3

Azodicarbonamide (CAS 123-77-3, C2H4N4O2), is a yellow to orange crystalline powder, widely used in the food industry as a blowing agent for the production of foamed plastics and rubber. It is also utilized as a flour bleaching agent and dough conditioner. Azodicarbonamide has the special property of decomposing at elevated temperatures, releasing nitrogen gas, which creates a foaming effect in various materials. This compound plays a crucial role in the production of expanded plastics, such as foam insulation, shoe soles, and yoga mats, as well as in the manufacturing of bread and other baked goods.
