CAS 99-63-8: Isophthaloyl chloride

Isophthaloyl chloride is a reactive and toxic chemical that is used in the production of polymers. It has a high resistance to water vapor, but is readily soluble in water. Isophthaloyl chloride is not stable at high temperatures and decomposes at about 150°C. Isophthaloyl chloride can be used as a model system for studying the transport properties of trifluoroacetic acid because it has similar chemical and physical properties.

Isophthaloyl dichloride is used in a variety of performance polymers and fibers, where it impacts flame resistance, temperature stability, chemical resistance, and flexibility. In addition, it is an effective stabilizer for urethane prepolymers due to its ability to scavenge water. Also used in aromatic fiber raw materials.
