3-Bromobiphenyl CAS 2113-57-7

1. 3-Bromobiphenyl is primarily used as an intermediate in organic synthesis, particularly in cross-coupling reactions (e.g., Suzuki, Heck) to introduce meta-substituted biphenyl motifs into complex molecules for pharmaceuticals, agrochemicals, and materials.
2. 3-Bromobiphenyl CAS 2113-57-7 serves as a building block for liquid crystals, organic semiconductors, and OLED materials due to its conjugated biphenyl structure and bromine reactivity.
3. 3-Bromobiphenyl functions as a precursor for flame retardants, polymer additives, and specialty chemicals in industrial applications.

1. Store 3-bromobiphenyl in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed, amber glass containers to prevent degradation.
2. Keep 3-bromobiphenyl CAS 2113-57-7 separate from strong oxidizing agents, strong bases, and reactive metals to prevent hazardous decomposition or violent reactions.
3. Handle 3-bromobiphenyl 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 3-bromobiphenyl CAS 2113-57-7 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. 3-Bromobiphenyl is harmful if swallowed, inhaled, or absorbed through the skin, and may cause skin irritation, serious eye damage, and respiratory tract irritation.
2. 3-Bromobiphenyl CAS 2113-57-7 may release toxic bromine vapors upon heating or decomposition; prolonged or repeated exposure may affect the respiratory system and other organs.
3. Always handle 3-bromobiphenyl in a certified fume hood or with adequate local exhaust, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
