Description

Methyl Perfluoroisobutyl Ether CAS NO 163702-08-7 is a highly volatile perfluorinated ether compound characterized by its exceptional chemical and thermal stability. This unique profile makes it a valuable intermediate and functional fluid in advanced industrial applications where inertness and low surface tension are critical. It is primarily sought by manufacturers in the electronics, aerospace, and specialty chemical sectors for demanding processes.

Application

• As a heat transfer fluid or dielectric coolant in high-performance electronics and aerospace systems.
• As a key intermediate in the synthesis of specialized fluorinated surfactants and polymers.
• As a solvent or carrier fluid for precision deposition and cleaning applications in semiconductor manufacturing.
• In the formulation of specialty lubricants and greases for extreme environments (e.g., high vacuum, oxidative conditions).
• As a tracer gas or testing medium in leak detection and fluid dynamics research due to its volatility and inertness.
• Potential use in fire suppression systems as a component of clean agent formulations.

Quality Control

Our Methyl Perfluoroisobutyl Ether is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to verify identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) documenting all relevant specifications are provided to ensure traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its high volatility, ensure containers are kept upright and sealed when not in use to prevent loss and maintain purity. Recommended storage temperature is 2-25°C.
