Trifluoromethyl Iodide (CAS 2314-97-8), commercially known as FIC-1311 or CF3I, is a colorless, odorless, and non-flammable gas. At room temperature and standard pressure, it is gaseous but is typically stored as a liquid under its own vapor pressure in cylinders. Trifluoromethyl Iodide (CAS 2314-97-8) is a significant "green" chemical due to its extremely short atmospheric lifetime and negligible Ozone Depletion Potential (ODP). It is widely utilized across the electronics, chemical synthesis, and fire safety industries as a high-performance, sustainable alternative to legacy halon gases and less efficient etching agents.
Environmentally Sustainable: Features an exceptionally low Global Warming Potential (GWP) and near-zero ODP, making it a compliant choice for modern environmental regulations.
High Extinguishing Efficiency: Recognized as a premier clean-agent fire suppressant for protecting sensitive electronic equipment and aviation assets.
Precision Semiconductor Etching: Provides high selectivity and superior etching ratios for silicon-based wafers in advanced microchip manufacturing.
Versatile Chemical Intermediate: Serves as a primary source for the trifluoromethyl group in the synthesis of specialized industrial chemicals and polymers.
Excellent Dielectric Properties: Its high dielectric strength makes it suitable for use as an insulating gas in high-voltage electrical switchgear.
High Purity (greater than or equal to 99.9%): Chemfine ensures electronic-grade purity to prevent contamination in sensitive manufacturing processes.
Fire Suppression Systems
Used as a gaseous clean agent in fire extinguishers for areas containing high-value electronics, telecommunications gear, and aviation components.
Semiconductor Plasma Etching
Functions as a reactive ion etching gas in the fabrication of microelectronics, offering high precision and vertical profile control on silicon substrates.
Organic Trifluoromethylation Reagent
Serves as a critical building block in organic synthesis to introduce the trifluoromethyl (CF3) group into various molecular frameworks.
High-Voltage Dielectric Insulation
Utilized as an insulating gas in electrical power distribution equipment, providing high dielectric strength and arc-quenching capabilities.
Industrial Aerosol Propellant
Acts as a specialized, non-flammable propellant for high-end industrial aerosols where chemical stability and safety are paramount.
Standard industrial packaging options for Trifluoromethyl Iodide include:
10kg or 20kg high-pressure seamless steel cylinders (Standard industrial grade).
50kg large-capacity gas cylinders for semiconductor manufacturing lines.
Tonne Tanks for large-scale fire suppression system installations.
Small lecture bottles for laboratory research and development.
All cylinders are equipped with high-integrity valves and are shipped in accordance with international compressed gas regulations.
Trifluoromethyl Iodide should be stored in a cool, dry, and well-ventilated dedicated gas storage area. Cylinders must be kept upright and securely fastened to prevent falling. Store away from direct sunlight, heat sources, and open flames. Although non-flammable, the cylinders are under high pressure and should be protected from physical damage. Keep away from strong oxidizing agents and molten alkali metals. The product is chemically stable with an indefinite shelf life if the cylinder integrity is maintained.
