1,4-dibromo-2,5-diiodobenzene(CAS: 63262-06-6)

1,4-Dibromo-2,5-diiodobenzene is a solid with a crystalline form. Its molecular weight is approximately 627.92 g/mol. It has low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is highly reactive due to the presence of bromine and iodine functionalities, making it susceptible to hydrolysis and substitution reactions.

1,4-Dibromo-2,5-diiodobenzene is typically synthesized via the nucleophilic aromatic substitution of 1,4-dibromobenzene with iodine. This process involves the use of a Lewis acid catalyst such as aluminum chloride to enhance the reactivity. The reaction is carried out in dichloromethane or another suitable solvent, yielding a product with a high selectivity and good yield.

1,4-Dibromo-2,5-diiodobenzene is used in the pharmaceutical industry for the synthesis of certain intermediates and drugs. It is also utilized in the polymer industry as a monomer or for modifying the properties of polymers. Additionally, it has applications in the semiconductor industry for its unique electronic properties and in sensors due to its reactivity.

When handling 1,4-dibromo-2,5-diiodobenzene, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to minimize the inhalation of fumes. Spills should be cleaned up using appropriate absorbents, and the area should be thoroughly cleaned. Always refer to the safety data sheet (SDS) for specific handling and disposal instructions.
