Product Name:3,3',4,4'-Biphenyltetracarboxylic Dianhydride
English Name:3,3',4,4'-Biphenyltetracarboxylic Dianhydride
CAS No.:2420-87-3
Aliases:BPDA, s-BPDA, 3,3',4,4'-Biphenyltetracarboxylic Acid Dianhydride
Molecular Formula:C16H6O6
Physical Properties:White to off-white crystalline powder; melting point approximately 300°C. Insoluble in water; readily soluble in strong polar organic solvents such as DMF, DMSO and NMP. Hygroscopic in moist air and slowly hydrolyzes to biphenyltetracarboxylic acid.
Uses:Mainly used as a key dianhydride monomer for polyimide synthesis. It reacts with diamines to produce polyimides, and is suitable for high-heat-resistant polyimide films, coatings, adhesives and composite materials. It is also used in alignment layers and insulating packaging materials in microelectronics.
Technical Specifications:
Appearance: white to off-white crystalline powder
Assay (GC): ≥98.0%
Melting point: 295–303°C
Loss on drying: ≤0.5%
Solubility: soluble in strong polar organic solvents such as DMF, DMSO and NMP
