Overview
3,4,5,6-Tetrafluorophthalonitrile is a highly fluorinated aromatic intermediate primarily synthesized via nucleophilic substitution of phthalonitrile with anhydrous hydrogen fluoride. It serves as a critical precursor for advanced liquid crystals and high-performance polymers. Molecular Formula: C8F4N2; CAS No.: 1790-25-4.
Application
- Liquid crystal displays (LCD) manufacturing for dielectric stability.
- Synthesis of polyimides for aerospace thermal insulation.
- Production of specialized agrochemical fungicides.
Precautions
Store in a dry, ventilated area below 25°C away from moisture. Use appropriate PPE including nitrile gloves and respirators due to potential skin irritation and toxicity upon hydrolysis.
