Description

3,3,4,4,7,7,8,8,8-Nonafluoro-1,5-Octadiene is a highly fluorinated diene compound, distinguished by its unique perfluoroalkyl segments and reactive alkene functionalities. This structure matters for delivering exceptional chemical stability, hydrophobicity, and oleophobicity, making it a valuable intermediate for synthesizing advanced fluorinated materials. It is primarily needed by R&D chemists and process engineers in the specialty chemical, polymer, and surface treatment industries seeking to incorporate high-performance fluorinated properties into their products.

Application

• Fluoropolymer Modification: Serves as a key monomer or cross-linking agent for introducing perfluoroalkyl side chains into polymers, enhancing surface properties like oil and water repellency.
• Specialty Surfactants & Coatings: Used in the synthesis of high-performance fluorosurfactants and additives for coatings, inks, and films requiring low surface energy and chemical resistance.
• Pharmaceutical & Agrochemical Intermediates: Acts as a building block for creating novel fluorinated active ingredients or prodrugs, leveraging the metabolic stability imparted by fluorine atoms.
• Advanced Material Research: Employed in academic and industrial R&D for developing new fluorinated elastomers, sealants, and electronic materials.
• Liquid Repellent Finishes: A precursor for treatments applied to textiles, leather, and filtration media to achieve durable stain and liquid resistance.

Quality Control

Our 3,3,4,4,7,7,8,8,8-Nonafluoro-1,5-Octadiene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases and fluorides. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
