4-Bromo-4'-iodobiphenyl CAS 105946-82-5

1. 4-Bromo-4'-iodobiphenyl is primarily used as a versatile monomer or intermediate in the synthesis of conjugated polymers, liquid crystals, and organic electronic materials such as OLEDs and semiconductors.
2. 4-Bromo-4'-iodobiphenyl CAS 105946-82-5 serves as a key building block in cross-coupling reactions (e.g., Suzuki, Sonogashira) to produce asymmetrically substituted biphenyl derivatives for pharmaceuticals and agrochemicals.
3. 4-Bromo-4'-iodobiphenyl functions as a precursor for metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and other advanced functional materials.

1. Store 4-bromo-4'-iodobiphenyl in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed, amber glass containers to prevent degradation and halogen liberation.
2. Keep 4-bromo-4'-iodobiphenyl CAS 105946-82-5 separate from strong oxidizing agents, strong bases, and reactive metals to prevent hazardous decomposition or violent reactions.
3. Handle 4-bromo-4'-iodobiphenyl with care using non-sparking tools and grounded equipment; ensure containers are clearly labeled and stored in a dedicated, secure area.

1. Immediately isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; avoid direct contact and prevent the material from entering drains or soil.
2. Carefully collect spilled 4-bromo-4'-iodobiphenyl CAS 105946-82-5 using a clean, dry tool or a HEPA-filter vacuum cleaner, and place it into a sealed, labeled container for disposal as hazardous chemical waste.
3. Clean the contaminated surface thoroughly with a suitable solvent or detergent under controlled conditions; collect all contaminated materials and dispose of them in full compliance with local, national, and international regulations for halogenated hazardous waste.

1. 4-Bromo-4'-iodobiphenyl is harmful if swallowed, inhaled, or absorbed through the skin, and may cause skin irritation, serious eye damage, and respiratory tract irritation.
2. 4-Bromo-4'-iodobiphenyl CAS 105946-82-5 may release toxic iodine or bromine vapors upon heating or decomposition; prolonged or repeated exposure may affect the thyroid gland and other organs.
3. Always handle 4-bromo-4'-iodobiphenyl in a certified fume hood or with adequate local exhaust, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
