Description

1,1,2,2-Tetrafluoroethyl 2,2,2-Trifluoroethyl Ether is a high-purity fluorinated ether compound valued for its unique combination of chemical inertness and high volatility. This makes it an essential intermediate and specialty solvent in advanced manufacturing processes where thermal stability and low surface energy are critical. It is primarily sought by R&D laboratories and industrial producers in the electronics, pharmaceutical, and specialty materials sectors for applications requiring precise chemical performance.

Application

• Electronics Manufacturing: As a precision cleaning agent or solvent in the production of semiconductors, printed circuit boards, and electronic components.
• Pharmaceutical Synthesis: As a fluorinated building block or specialized reaction medium in the development of active pharmaceutical ingredients (APIs).
• Specialty Coatings & Polymers: As a monomer or additive to impart oil, water, and stain repellency to high-performance polymers and surface coatings.
• Refrigerants & Heat Transfer Fluids: As a component in next-generation, low-global-warming-potential (GWP) refrigerant blends.
• Chemical Research & Development: As a versatile fluorinated solvent for reactions sensitive to moisture or requiring non-nucleophilic conditions.
• Aerosol Propellants: Utilized in specialty aerosol formulations for its favorable vapor pressure and stability.

Quality Control

Our 1,1,2,2-Tetrafluoroethyl 2,2,2-Trifluoroethyl Ether is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and NMR analysis, to ensure high purity and consistency that meets or exceeds industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee supply reliability and traceability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and open flame. Recommended storage temperature is 2-8°C to minimize vapor pressure and maintain product integrity. Keep container tightly sealed when not in use.
