Description

Perfluoro-1,3-Dimethylcyclohexane is a fully fluorinated, saturated cyclic hydrocarbon known for its exceptional chemical inertness and thermal stability. This compound is valued for its unique combination of high volatility and low surface tension, making it an ideal candidate for specialized applications requiring a non-reactive, volatile medium. It is primarily sought by industries involved in advanced electronics manufacturing, precision cleaning, and high-performance heat transfer systems.

Application

• Electronics Cooling & Heat Transfer: Used as a high-performance dielectric coolant in immersion cooling systems for servers, power electronics, and high-density computing due to its thermal stability and electrical insulating properties.
• Precision Cleaning & Degreasing: Serves as an effective solvent for removing particulate and organic contaminants from sensitive components in aerospace, semiconductor, and optical manufacturing without leaving residues.
• Chemical Vapor Deposition (CVD) & Etching: Acts as a precursor or carrier fluid in semiconductor fabrication processes where high purity and controlled volatility are critical.
• Leak Testing & Tracer Fluid: Utilized in sensitive leak detection systems for HVAC, refrigeration, and industrial piping because of its high volatility and detectability.
• Specialty Solvent Formulations: Incorporated into formulations for coatings, lubricants, and release agents where chemical resistance and volatility are required.
• Laboratory & Analytical Reagent: Employed as a standard or solvent in gas chromatography, spectroscopy, and other analytical techniques.

Quality Control

Our Perfluoro-1,3-Dimethylcyclohexane is manufactured under stringent controls to ensure batch-to-batch consistency and high purity, typically exceeding 99% (GC area). Quality is verified through a comprehensive suite of analytical methods including Gas Chromatography (GC), NMR spectroscopy, and Karl Fischer titration for moisture content. A Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with each shipment to 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 open flames. Due to its high volatility, ensure containers are kept upright and sealed when not in use to prevent evaporation and contamination. Recommended storage temperature is 15-25°C.
