Description

1,1,1,2,2,5,5,6,6-Nonafluorooctane is a high-purity, highly volatile fluorinated alkane with a unique combination of chemical inertness and favorable physical properties. Its value lies in its role as a versatile, high-performance solvent and process fluid in demanding applications where traditional hydrocarbons are unsuitable. This compound is essential for manufacturers in the electronics, specialty chemical, and advanced materials sectors seeking reliable, non-reactive media for precision cleaning, heat transfer, and formulation.

Application

• Precision Cleaning Agent: Used for critical cleaning of electronic components, optical lenses, and precision mechanical parts where low surface tension and zero residue are required.
• Heat Transfer Fluid: Serves as a stable, non-flammable cooling medium in specialized industrial and laboratory equipment.
• Solvent for Specialty Formulations: Acts as an inert carrier or solvent in the production of fluoropolymers, coatings, and high-performance lubricants.
• Dielectric Fluid: Employed in high-voltage and high-frequency electrical applications due to its excellent insulating properties.
• Chemical Reaction Medium: Provides an inert, non-polar environment for sensitive fluorination and other specialty chemical synthesis reactions.
• Standard & Reference Material: Used in analytical laboratories for calibration and as a standard in gas chromatography and mass spectrometry.

Quality Control

Our 1,1,1,2,2,5,5,6,6-Nonafluorooctane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) and nuclear magnetic resonance (NMR), to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are provided and available upon request.

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 highly volatile nature, ensure containers are kept upright and sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 15-25°C.
