N,N-Dinitroso-p-phenylenediamine-N,N-diacetic Acid Dimethyl Ester

N,N-Dinitroso-p-phenylenediamine-N,N-diacetic Acid Dimethyl Ester, commonly known as DPPD, is a chemical compound that is primarily used as an antioxidant in the rubber and petroleum industries. It is a yellow to brown crystalline powder that is soluble in ethanol, acetone, and chloroform. It is also used as an intermediate in the synthesis of other organic compounds. DPPD works by scavenging free radicals that can cause oxidative degradation of rubber and petroleum products. This degradation can lead to a loss of physical and mechanical properties, as well as a reduction in the lifespan of the products. By using DPPD, the products are protected from these free radicals, and their lifespan is extended. In terms of chemical information, DPPD has a molecular formula of C16H18N4O6, and a molecular weight of 370.34 g/mol. It has a melting point of 135-140°C and a boiling point of 483.7°C. It is classified as a hazardous substance, with potential hazards including skin and eye irritation, respiratory tract irritation, and environmental toxicity. Overall, DPPD is a valuable chemical compound that plays an important role in the preservation and protection of rubber and petroleum products. Its antioxidant properties make it a valuable tool in the industries that rely on these materials.
