Description

T-Butyl 1,1,2,2-Tetrafluoroethyl Ether is a specialized fluorinated ether compound, identified by CAS number 659-98-3. This chemical is valued for its unique combination of volatility and fluorinated structure, making it a versatile intermediate and solvent in advanced chemical synthesis. It is primarily sought after by R&D laboratories and industrial manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors for applications requiring inert, high-performance reaction media or building blocks.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring fluorinated motifs for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where the introduction of fluorine atoms can significantly improve product efficacy and environmental profile.
• Specialty Solvent: Acts as a high-performance, low-boiling solvent for sensitive reactions in organic synthesis, including polymerization and catalysis, due to its chemical inertness and high volatility.
• Electrolyte Additive: Investigated for use as a stabilizing additive in lithium-ion battery electrolytes to improve performance and safety at high voltages.
• Refrigerant & Propellant Research: Explored as a component in next-generation, low-global-warming-potential (GWP) refrigerant blends and precision propellant formulations.
• Surface Modification Agent: Utilized to introduce fluorinated groups onto material surfaces, enhancing properties like hydrophobicity, oleophobicity, and chemical resistance.

Quality Control

Our T-Butyl 1,1,2,2-Tetrafluoroethyl Ether is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure compliance with exacting purity and consistency standards. A comprehensive Certificate of Analysis (COA) detailing identity, assay, purity, and impurity profiles is provided with every shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for long-term stability.
