Application

1. DSDA CAS 2540-99-0 serves as a core monomer for synthesizing sulfone-containing polyimide resins with excellent thermal and chemical resistance.

2. Applied 3 3′ 4 4′-DIPHENYLSULFONETETRACARBOXYLIC DIANHYDRIDE in manufacturing high-performance insulating materials for high-temperature electronic components and aerospace equipment.

3. Utilized as a building block for producing corrosion-resistant polymer composites used in harsh industrial environments.

Storage and Precautions

3,3',4,4'-Diphenylsulfonetetracarboxylic Dianhydride should be stored in a tightly sealed, moisture-proof container at 15–25°C, in a cool, dry and well-ventilated area away from direct sunlight and heat sources. It is highly susceptible to hydrolysis when exposed to moisture, so keep it isolated from water, humid environments, strong acids and bases to prevent quality deterioration.

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.
