Used as a highly effective radical initiator in polymerization processes, especially in aqueous systems. It is commonly applied in the synthesis of water-soluble polymers, such as polyacrylamides, which are essential in water treatment, enhanced oil recovery, and paper manufacturing. Its ability to decompose into nitrogen gas and generate free radicals under mild conditions makes it suitable for controlled reactions at low to moderate temperatures. Also utilized in biochemical applications, such as protein labeling and cross-linking, due to its water solubility and predictable decomposition behavior.
