1,2,4,5-Tetrabromobenzene

Description:

1,2,4,5-Tetrabromobenzene is an aromatic compound characterized by the presence of four bromine atoms attached to a benzene ring at the 1, 2, 4, and 5 positions. Its molecular formula is C6H2Br4, indicating a high degree of bromination, which significantly influences its physical and chemical properties. This compound typically appears as a colorless to pale yellow solid and is known for its high density and low volatility. It is relatively insoluble in water but soluble in organic solvents such as acetone and chloroform. 1,2,4,5-Tetrabromobenzene is primarily used in research and industrial applications, including as a flame retardant and in the synthesis of other brominated compounds. Due to the presence of multiple bromine atoms, it exhibits notable stability and resistance to degradation, but it may pose environmental and health risks, necessitating careful handling and disposal. Its chemical behavior is influenced by the electron-withdrawing nature of the bromine substituents, which can affect reactivity in electrophilic substitution reactions.
