Description

1H-Nonafluorobutane CAS NO 375-17-7 is a highly volatile fluorinated hydrocarbon solvent with a unique combination of chemical inertness and low surface tension. This compound is valued for its excellent solvency power for specific materials and its favorable environmental profile as a non-ozone-depleting substance. It serves as a critical processing agent in advanced electronics manufacturing, precision cleaning, and specialty chemical synthesis for industries demanding high-performance, low-residue solutions.

Application

• Precision Cleaning Agent: Used for defluxing and degreasing sensitive electronic components, optical lenses, and medical devices where low residue and rapid drying are critical.
• Specialty Solvent: Acts as a reaction medium or carrier solvent in pharmaceutical synthesis and fine chemical manufacturing where chemical stability is required.
• Aerosol Propellant: Employed in formulated aerosol products, including dusters and spray cleaners, as a non-flammable, low-GWP (Global Warming Potential) alternative.
• Refrigerant & Heat Transfer Fluid: Used in specialized low-temperature cooling systems and as a component in refrigerant blends.
• Foam Blowing Agent: Utilized in the production of insulating foams, particularly for applications requiring specific cell structure and thermal properties.
• Dielectric Fluid: Suitable for use in certain high-voltage and testing equipment due to its electrical insulating properties.
• Chemical Intermediate: Serves as a building block in the synthesis of more complex fluorinated compounds, surfactants, and polymers.
