Used primarily as a blowing agent in the production of foamed polymers, particularly in the manufacture of expanded plastics like PVC and rubber. It decomposes at elevated temperatures to release nitrogen gas, which creates a cellular structure within the material, enhancing insulation properties and reducing weight. Additionally, it finds application in the synthesis of organic compounds, serving as a reagent in chemical reactions to introduce sulfonohydrazide groups. Its thermal decomposition characteristics make it valuable in industries requiring controlled foaming processes.
