Applications

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.

Notes

Incompatible with strong bases and strong oxidizing agents. It is sensitive to moisture. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Moisture sensitive.
