Description

2-Methyl-4,4,5,5,6,6,7,7,7-Nonafluorohept-2-Ene is a high-value fluorinated olefin characterized by its unique perfluoroalkyl chain and terminal double bond. This structure makes it a critical advanced intermediate for synthesizing specialty materials with exceptional chemical resistance, thermal stability, and low surface energy. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel fluorinated compounds and functional polymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of fluorinated active pharmaceutical ingredients (APIs) to enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key building block for creating novel fluorinated pesticides and herbicides with improved efficacy and environmental profile.
• Fluoropolymer Modification: Acts as a comonomer or grafting agent to introduce perfluoroalkyl side chains, enhancing the oil and water repellency, and chemical resistance of polymers.
• Surface Treatment & Coatings: Employed in the formulation of high-performance coatings, sealants, and surface modifiers to achieve ultra-low surface energy and anti-fouling properties.
• Specialty Fluids & Lubricants: A precursor for high-performance fluorinated fluids and lubricants used in demanding industrial and aerospace applications.
• Electronics Industry: Potential use in the deposition of fluorocarbon thin films or as a precursor for etching gases in semiconductor manufacturing.

Quality Control

Every batch of our 2-Methyl-4,4,5,5,6,6,7,7,7-Nonafluorohept-2-Ene is produced and tested under a strict quality management system. We employ advanced analytical techniques including GC, GC-MS, NMR, and FTIR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizers and bases. For long-term storage, maintaining the container under an inert atmosphere (e.g., nitrogen or argon) is recommended to preserve product integrity. Recommended storage temperature: 2-8°C.
