Biphenyl-4 4′-dicarboxylic Acid CAS 787-70-2

1. Biphenyl-4,4'-dicarboxylic acid CAS 787-70-2 is primarily used as a key monomer in the synthesis of high-performance polymers, such as polyesters and polyamides, particularly for liquid crystalline polymers (LCPs).
2. Biphenyl-4 4′-dicarboxylic acid serves as a versatile building block for metal-organic frameworks (MOFs), coordination polymers, and other advanced materials.
3. This compound is also utilized in research for developing organic semiconductors, dyes, and specialty fine chemicals.

1. Store biphenyl-4,4'-dicarboxylic acid CAS 787-70-2 in a cool, dry, well-ventilated place, away from heat and incompatible materials such as strong oxidizing agents and strong bases.
2. Keep Biphenyl-4 4′-dicarboxylic acid the container tightly closed to prevent moisture absorption and contamination.
3. Handle with appropriate personal protective equipment (PPE), including gloves and safety goggles, to minimize dust inhalation and skin contact.

1. Isolate the spill area and wear suitable protective equipment (gloves, safety glasses, dust mask if needed).
2. Collect Biphenyl-4 4′-dicarboxylic acid with a clean, dry tool and place it in a suitable container for disposal.
3. Prevent the material from entering drains or the environment. Clean the area with water and detergent.

1. Biphenyl-4,4'-dicarboxylic acid CAS 787-70-2 may be harmful if swallowed or inhaled as dust, and can cause skin and eye irritation.
2. Biphenyl-4 4′-dicarboxylic acid is not highly flammable but may decompose at high temperatures to produce irritating fumes.
3. Always consult the official biphenyl-4,4'-dicarboxylic acid Safety Data Sheet (SDS) for comprehensive hazard, handling, and regulatory information.
