Nonafluorobutyl Methyl Ether (CAS 163702-07-6 / 163702-08-7 | HFE-7100 Series)
Nonafluorobutyl Methyl Ether (commonly designated as Methyl Nonafluorobutyl Ether or HFE-7100) is a zero-ozone-depleting, clear, colorless, low-odor hydrofluoroether solvent. Formulated as a proprietary mixture of two inseparable isomers—methyl nonafluorobutyl ether ($C_4F_9OCH_3$) and methyl nonafluoroisobutyl ether ($(CF_3)_2CFCF_2OCH_3$)—this non-flammable liquid is engineered specifically to replace ozone-depleting substances (ODSs) such as CFC-113, HCFC-141b, and high GWP hydrofluorocarbons (HFCs).

Pioneering Next-Generation Eco-Friendly Hydrofluoroether (HFE) Solutions for the Post-PFAS Era
Global regulatory bodies including the EU ECHA (REACH restrictions), US EPA (SNUR provisions), and Asia-Pacific environmental ministries are enforcing stringent phase-downs of legacy Perfluorocarbons (PFCs), Hydrochlorofluorocarbons (HCFCs), and high-GWP HFCs. Nonafluorobutyl Methyl Ether serves as an optimal drop-in replacement that meets upcoming ESG mandates while preserving high solvency power and material compatibility.
With the exponential expansion of high-density AI compute nodes, graphics processing units (GPUs), and supercomputer architectures, air and traditional water-block cooling reach thermal limits. Nonafluorobutyl Methyl Ether operates flawlessly in direct-to-chip two-phase immersion cooling systems, offering high heat-transfer capacity, excellent dielectric safety, low maintenance overhead, and non-flammable operation.
As semiconductor node dimensions scale below 2nm, sub-nanometer particle residue during EUV photolithography and wafer etching leads to severe yield losses. JIMPOCHEM’s high-purity Nonafluorobutyl Methyl Ether (NVR < 1 ppm, metal ion impurities < 10 ppt) is customized for sub-2nm rinse processes, photoresist stripping carriers, and ultra-clean wafer surface drying applications.
Engineered to deliver unmatched performance across critical high-tech manufacturing sectors
Nonafluorobutyl Methyl Ether exhibits optimal physical characteristics for vapor degreasing equipment. With its low latent heat of vaporization and high fluid density, it thoroughly penetrates intricate micro-geometries, remove fluorinated greases, rosin fluxes, particulate contaminants, and synthetic oils without damaging sensitive metallic substrates or organic polymers.
In aerospace flight control systems, satellite payloads, and high-precision laser optics, organic residues cause catastrophic signal attenuation. Nonafluorobutyl Methyl Ether leaves zero measurable particulate residue upon rapid evaporation, making it the benchmark standard fluid for cleaning gyro-components, optical lenses, and aerospace fuel system assemblies.
As electric vehicle (EV) battery packs increase energy density, thermal runaway risk escalates. Nonafluorobutyl Methyl Ether functions as a specialized non-flammable electrolyte additive and immersion flame-retardant cooling medium, effectively suppressing electrolyte combustion and maintaining uniform thermal distribution during fast charging cycles.
Due to its high solubility for perfluoropolyether (PFPE) lubricants, fluorosilicones, and hydrophobic coatings, Nonafluorobutyl Methyl Ether serves as an ideal carrier solvent. It enables ultra-thin, uniform surface deposition on hard disk drive media, medical catheters, needle siliconization, and display anti-fingerprint coatings.
