2,2'-Dibromo-4,4'-bis(2-methyl-2-propanyl)biphenyl(CAS: 70728-93-7)

2,2'-Dibromo-4,4'-bis(2-methyl-2-propanyl)biphenyl is a crystalline solid with a high molecular weight, making it less soluble in common organic solvents. It exhibits low reactivity, which is typical for biphenyl derivatives with bromine substituents. It is stable under normal conditions but should be stored in a cool, dark place to prevent photodegradation.

2,2'-Dibromo-4,4'-bis(2-methyl-2-propanyl)biphenyl is synthesized through a multistep process involving bromination of a starting biphenyl derivative followed by alkylation with 2-methylpropane. The reaction typically requires a phase transfer catalyst and is carried out under mild conditions to achieve good yield and selectivity.

2,2'-Dibromo-4,4'-bis(2-methyl-2-propanyl)biphenyl is used in the pharmaceutical industry as a precursor in the synthesis of certain drugs. It is also employed in the polymer industry for stabilizing polymers against UV light and in the semiconductor industry for its unique electronic properties.

When handling 2,2'-Dibromo-4,4'-bis(2-methyl-2-propanyl)biphenyl, wear appropriate personal protective equipment (PPE) including gloves and goggles. Store it in a cool, well-ventilated area away from direct sunlight. In case of spill, immediately clean up using appropriate absorbents and follow local safety guidelines. Always consult the Safety Data Sheet (SDS) for specific handling instructions.
