4-Bromo-2-iodobenzyl bromide(CAS: 885681-96-9)

4-Bromo-2-iodobenzyl bromide is a crystalline solid with a molecular weight of approximately 416.09 g/mol. It has low solubility in water but is more soluble in organic solvents like dichloromethane and acetonitrile. This compound is highly reactive due to the presence of bromine and iodine substituents. It is known for its strong electrophilic character and can undergo nucleophilic substitution reactions easily.

4-Bromo-2-iodobenzyl bromide can be synthesized through the bromination of 2-iodobenzyl alcohol using N-bromosuccinimide (NBS) in the presence of a radical initiator like benzoyl peroxide. The reaction is typically carried out in a chloroform or dichloromethane solvent at room temperature. The product can be isolated by recrystallization from a suitable solvent.

4-Bromo-2-iodobenzyl bromide is used in the pharmaceutical industry for the synthesis of certain drugs and intermediates. It also finds applications in the polymer industry for the modification of polymers, and in the semiconductor industry for the fabrication of organic thin films. Additionally, it can be used in the development of sensors and as a reagent in organic synthesis.

When handling 4-Bromo-2-iodobenzyl bromide, it is essential to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. The compound should be handled in a well-ventilated area or in a fume hood to minimize exposure to bromine and iodine vapors. Spills should be cleaned up immediately using appropriate absorbents, and the area should be thoroughly rinsed with water. A Safety Data Sheet (SDS) should always be consulted for detailed safety information and emergency procedures.
