Tetrabromobutane, with the CAS number 2657-67-2, is a halogenated organic compound characterized by the presence of four bromine atoms attached to a butane backbone. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its specific form and purity. It is known for its high density and low volatility, making it useful in various applications, including as a flame retardant and in organic synthesis. Tetrabromobutane is relatively stable under normal conditions but can undergo reactions typical of alkyl halides, such as nucleophilic substitution. Due to the presence of bromine, it exhibits significant reactivity, particularly in the presence of strong nucleophiles. Safety considerations are important when handling this substance, as it may pose health risks through inhalation or skin contact, and proper protective measures should be employed. Additionally, its environmental impact should be assessed, as halogenated compounds can have implications for ecological systems.

Meso-1,2,3,4-Tetrabromobutane is a nitronium cation that is produced by the oxidation of butenyl nitryl chloride. The evolution of the nitronium cation is dependent on the constants of the reaction and the reactants. The oxidation process can be carried out in two ways: transfer or direct addition. In either case, vinyl groups are transferred to oxygen to give an unstable product with a dihedral angle of 180°. Thermal analysis has shown that solvents such as ethylene will react with meso-1,2,3,4-tetrabromobutane to form nitroethane and 2-chloropropene.
