4-Bromo-4'-chloro-1,1'-biphenyl(CAS: 23055-77-8)

4-Bromo-4'-chloro-1,1'-biphenyl (CAS: 23055-77-8) falls under the regulatory scope of GHS for classification as a hazardous substance. Specific requirements include labeling, storage, and handling under REACH regulations for safety data sheets (SDS). FDA and EPA might also have specific guidelines for its use in pharmaceuticals and chemical products.

For synthesis, 4-Bromo-4'-chloro-1,1'-biphenyl (CAS: 23055-77-8) can be replaced by similar brominated and chlorinated biphenyls such as 4-Bromo-1,1'-biphenyl or 4-Chloro-1,1'-biphenyl. Alternative reagents like brominating or chlorinating agents can also be considered depending on the specific chemical transformation needed.

The market for 4-Bromo-4'-chloro-1,1'-biphenyl (CAS: 23055-77-8) is driven by its use in the pharmaceutical and materials science industries. Research trends are focusing on its potential in drug development and polymer synthesis. However, due to environmental concerns, there is a trend towards developing safer alternatives and reducing reliance on chlorinated and brominated compounds.

Waste containing 4-Bromo-4'-chloro-1,1'-biphenyl (CAS: 23055-77-8) should be collected in sealed containers and managed according to hazardous waste regulations. Incineration in controlled facilities or professional waste disposal services are recommended to ensure the compound is properly disposed of. Proper environmental protection precautions include minimizing exposure and ensuring the waste is handled by qualified personnel.
