1,3,5-trinitro-benzene, also known as trinitrobenzene (TNB), is an organic compound with the chemical formula C6H3N3O6. It is a derivative of benzene, where three nitro groups (-NO2) are attached to the benzene ring at the 1, 3, and 5 positions. TNB is a yellow crystalline solid with a melting point of 122-123°C. It is a powerful explosive and is used as a chemical intermediate in the synthesis of other explosives and propellants. Due to its high sensitivity to shock and friction, TNB is considered a hazardous substance and requires careful handling and storage. The compound with benzene refers to the mixture of TNB and benzene, which can be used as a solvent or a precursor in various chemical reactions.
