Widely used as a water-soluble free radical initiator in polymerization reactions, particularly in the production of high molecular weight polymers. It is effective in emulsion, suspension, and solution polymerizations due to its ability to decompose at low to moderate temperatures, generating radicals that initiate chain growth. Commonly applied in the synthesis of polyacrylamides, which are used in water treatment, papermaking, and enhanced oil recovery. Its cationic nature improves solubility and compatibility in acidic aqueous systems. Also utilized in biochemical applications for protein immobilization and cross-linking due to its ability to initiate polymerization under mild, biocompatible conditions. Stable in storage when kept cool and dry, but decomposes rapidly at elevated temperatures to release nitrogen gas, making it suitable for controlled initiation processes.
