Xylyl bromide, also known as 1,4-dibromoxylene, is an aromatic organic compound with the molecular formula C8H8Br2. It is a colorless liquid with a strong, pungent odor. Xylyl bromide is primarily used as an intermediate in the production of other chemicals, such as pharmaceuticals, dyes, and solvents. It is also used as a fumigant and as a flame retardant.

The production of xylyl bromide involves the reaction of p-xylene with bromine in the presence of a catalyst. The reaction is typically carried out in a batch reactor at elevated temperatures and pressures. The product is then purified by distillation.

Xylyl bromide is a toxic compound and can cause a variety of health effects, including skin and eye irritation, respiratory problems, and neurological damage. It is important to take appropriate safety precautions when working with this chemical, such as wearing protective clothing and using proper ventilation.

Xylyl bromide is a flammable liquid and should be stored in a cool, dry place away from sources of ignition. It is also important to keep xylyl bromide away from incompatible materials, such as strong oxidizing agents and bases.

The disposal of xylyl bromide should be done in accordance with local regulations. It is important to ensure that xylyl bromide is not released into the environment, as it can be harmful to aquatic life.
