Description

Perfluoroheptane (CAS 335-57-9) is a high-purity fluorinated hydrocarbon with the molecular formula C₇F₁₆ and IUPAC name 1,1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-hexadecafluoroheptane. This fully fluorinated, linear alkane exhibits exceptional chemical inertness, thermal stability, and low surface tension, making it ideal for specialized applications in research and industrial settings. Perfluoroheptane is a colorless, odorless liquid with a high density (∼1.7 g/mL) and is immiscible with water and most organic solvents. Its unique properties stem from the strong carbon-fluorine bonds, which confer resistance to oxidation, UV degradation, and extreme temperatures. Available in ≥98% purity, our product is rigorously tested for consistency, ensuring reliable performance in sensitive applications such as electronics, optics, and precision cleaning.

Key Features:

• Exceptional thermal and chemical stability
• Low surface tension and high dielectric strength
• Non-flammable and non-reactive with most chemicals
• High purity (≥98%) with minimal impurities
• Compatible with fluoropolymer and semiconductor processing
