4,5-Dibromo-o-xylene

Description:

4,5-Dibromo-o-xylene, with the CAS number 24932-48-7, is an organic compound belonging to the class of brominated aromatic hydrocarbons. It features a xylene backbone, which consists of a benzene ring with two methyl groups, and is substituted with two bromine atoms at the 4 and 5 positions relative to each other. This compound is typically a colorless to pale yellow liquid or solid, depending on temperature and purity. It is characterized by its relatively low solubility in water but higher solubility in organic solvents, making it useful in various chemical applications. The presence of bromine atoms enhances its reactivity, allowing it to participate in electrophilic substitution reactions and making it valuable in the synthesis of other chemical compounds. Additionally, 4,5-dibromo-o-xylene may exhibit biological activity, which necessitates careful handling and consideration of safety protocols during its use in laboratory or industrial settings. As with many brominated compounds, it is important to assess its environmental impact and potential toxicity.
