Properties

Molecular Formula: C10H4ClF15O2
Molecular Weight: 448.57 g/mol
Chemical Structure: The molecule consists of a perfluorinated octyl chain substituted with a 2-chloroacrylate functional group. This combination imparts unique fluorinated properties such as high chemical stability and low surface energy.

Boiling Point: Data is limited due to the specialty nature, but perfluorinated acrylates generally exhibit high thermal stability and low volatility.
Solubility: Sparingly soluble in water; soluble in fluorinated solvents, some organic solvents like acetone, and specific photoresist-compatible resins.

Key Chemical Features:

1. Perfluorooctyl group: Provides hydrophobicity, oleophobicity, and chemical resistance.
2. 2-Chloroacrylate group: Allows for polymerization and crosslinking in UV-curable systems and photoresist formulations.
3. Thermal and chemical stability: Resistant to acids, bases, and oxidation, making it suitable for high-performance electronic applications.

Industrial Applications

1. Semiconductor Industry:
   • Used as a surface-modifying monomer in advanced photoresists and anti-reflective coatings.
   • Imparts low surface energy to resist layers, improving pattern resolution and reducing defects in lithography processes.
2. Photoresist Industry:
   • Functions as a reactive monomer for UV-curable resists.
   • Enhances adhesion control and chemical resistance of patterned resists in high-precision photolithography.
3. Electronic Chemicals:
   • Acts as a specialty monomer in formulations requiring high fluorine content for non-wetting, chemical-resistant coatings.
   • Can be incorporated into polymer matrices to produce films or layers with exceptional stability in harsh chemical environments.

Safety and Handling

• Hazard Classifications: May cause skin and eye irritation; handle with appropriate personal protective equipment (PPE).
• Storage: Store in a cool, dry, and well-ventilated area away from strong oxidizers and open flames.
• Environmental Considerations: As a perfluorinated compound, it is persistent in the environment. Waste management must comply with local regulations on fluorochemicals.
