2. Applied Bis[(3 4-dicarboxylic Anhydride) Phenyl]terephthalate in manufacturing high-performance dielectric materials for advanced electronic devices and printed circuit boards.
3. Utilized as a cross-linking agent for enhancing the mechanical toughness and chemical stability of specialty polymer composites.
Storage and Precautions
Bis[(3 4-dicarboxylic anhydride)phenyl]terephthalate must be stored in a tightly sealed, moisture-proof and light-resistant container at 15–25°C, in a cool, dry and well-ventilated warehouse away from direct sunlight and heat sources. It is prone to hydrolysis when in contact with moisture, so it should be isolated from water, humid environments, strong acids and bases to prevent quality degradation.
During handling, wear chemical-resistant gloves, goggles and a lab coat, and operate in a fume hood to avoid dust inhalation and skin/eye contact. Reseal the container immediately after use. Dispose of waste strictly following local hazardous chemical regulations.
