2-Methyl-2-nitrosopropane dimer

2-Methyl-2-nitrosopropane dimer, also known as di-tert-butyl nitroxide (DTBN), is a stable free radical compound that is commonly used in organic chemistry as a radical scavenger and inhibitor. Its chemical formula is C12H24N2O2 and its molecular weight is 232.33 g/mol. DTBN is often used in polymerization reactions to control the radical polymerization process by removing unwanted radicals that may cause termination of the reaction. It is also used in the synthesis of various organic compounds such as pharmaceuticals, pesticides, and dyes. DTBN is a yellow to orange crystalline solid that is insoluble in water but soluble in organic solvents such as ethanol, ether, and chloroform. It has a melting point of 80-82°C and a boiling point of 155-157°C. DTBN is relatively stable at room temperature and can be stored for long periods. In terms of safety, DTBN is considered to be a low hazard chemical. It is not classified as a hazardous substance by any major regulatory agency and has a low toxicity. However, as with any chemical, proper handling and disposal procedures should be followed to minimize any potential risks.
