1,4-Dibromo(~2~H_4_)benzene(CAS: 4165-56-4)

1,4-Dibromo(~2~H_4_)benzene (CAS 4165-56-4) is a crystalline solid with a molecular weight of approximately 238.03 g/mol. It has low water solubility, with a solubility of about 0.02 g/L. Chemically, it is highly reactive due to the presence of bromine groups, making it susceptible to hydrolysis and other substitution reactions.

1,4-Dibromo(~2~H_4_)benzene is typically synthesized by the bromination of 1,4-benzenediol using bromine in the presence of a Lewis acid catalyst such as aluminum bromide (AlBr3) or iron(III) bromide (FeBr3). The reaction is exothermic and selective, yielding high purity dibrominated product with a yield of around 80-90%.

1,4-Dibromo(~2~H_4_)benzene is used in the pharmaceutical industry for the synthesis of certain drugs, in the semiconductor industry for photoresist materials, and in sensors as a detection component. It is also employed in polymer chemistry for developing novel materials with specific properties.

When handling 1,4-Dibromo(~2~H_4_)benzene (CAS 4165-56-4), use proper personal protective equipment (PPE) including gloves, goggles, and a lab coat. Work in a well-ventilated area or fume hood to minimize exposure. Store in a cool, dry place away from heat sources and incompatible materials. In case of spill, refer to the Safety Data Sheet (SDS) for specific procedures and contact a chemical spill response team if necessary.
