1 4-Diiodobenzene CAS 624-38-4

1. 1,4-Diiodobenzene is primarily used as a versatile building block in organic synthesis, particularly in cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira) to introduce para-substituted diiodoarene motifs into polymers, liquid crystals, and complex molecules.
2. 1,4-Diiodobenzene CAS 624-38-4 serves as a key intermediate in the synthesis of pharmaceuticals, agrochemicals, and organic electronic materials such as OLEDs and semiconductors.
3. 1,4-Diiodobenzene functions as a precursor for metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and other advanced porous materials.

1. Store 1,4-diiodobenzene in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed, amber glass containers to prevent degradation and iodine liberation.
2. Keep 1,4-diiodobenzene CAS 624-38-4 separate from strong oxidizing agents, strong bases, and reactive metals to prevent hazardous decomposition or violent reactions.
3. Handle 1,4-diiodobenzene 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 1,4-diiodobenzene CAS 624-38-4 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. 1,4-Diiodobenzene is harmful if swallowed, inhaled, or absorbed through the skin, and may cause skin irritation, serious eye damage, and respiratory tract irritation.
2. 1,4-Diiodobenzene CAS 624-38-4 may release toxic iodine vapors upon heating or decomposition; prolonged or repeated exposure may affect the thyroid gland and other organs.
3. Always handle 1,4-diiodobenzene in a certified fume hood or with adequate local exhaust, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
