3,3',5,5'-Tetrabromobiphenyl丨CAS 16400-50-3

1. Precursor for Flame Retardants

Used in the synthesis of brominated flame retardants, which are added to polymers, textiles, and electronics to reduce flammability.

The bromine atoms help interrupt combustion processes by releasing bromine radicals that quench free radicals in flames.

2. Organic Synthesis Intermediate

Serves as a building block for the preparation of polybrominated biphenyl derivatives, which can be further functionalized via cross-coupling reactions.

Used in the synthesis of liquid crystals, pharmaceuticals, and specialty polymers.

3. Material Science

Incorporated into organic electronic materials for modifying optical and electronic properties.

Brominated biphenyls often improve thermal stability and chemical resistance in materials.

4. Environmental and Toxicological Studies

As a brominated biphenyl, it is sometimes studied for its structural similarity to polybrominated diphenyl ethers (PBDEs), which are environmental contaminants.

Useful as a reference or model compound in toxicology research.

✅ High Thermal Stability

The tetrabrominated structure enhances thermal resistance, beneficial for high-temperature applications.

✅ Effective Flame Retardant Precursor

Bromine substituents impart flame-retardant properties when incorporated into polymers.

✅ Versatile Chemical Reactivity

The bromine atoms are reactive sites for substitution or cross-coupling reactions, enabling further molecular diversification.

✅ Enhanced Material Performance

Incorporation into polymers or materials enhances chemical resistance and durability.
