Description

4-(2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-Heptadecafluorononyl)-2,2-Dimethyl-1,3-Dioxolane is a high-value fluorinated acetal derivative, specifically engineered to introduce a long perfluoroalkyl chain into target molecules. This compound matters because its unique structure provides exceptional hydrophobicity, oleophobicity, and chemical stability, making it a critical building block for advanced materials. It is primarily needed by R&D chemists and manufacturers in the specialty chemical, advanced polymer, and surface treatment industries seeking to impart permanent low surface energy properties.

Application

• Fluorinated Polymer Synthesis: As a key monomer or modifier for creating polymers with enhanced oil, water, and stain resistance.
• Surface Modification Agents: Used to manufacture coatings for textiles, paper, and leather to achieve durable water and oil repellency (like in outdoor gear and protective apparel).
• Specialty Surfactants & Additives: Serves as a precursor for fluorosurfactants used in demanding applications such as fire-fighting foams and electronic coatings.
• Pharmaceutical & Agrochemical Intermediates: Acts as a building block in the synthesis of bioactive molecules where fluorination can improve metabolic stability and membrane permeability.
• Liquid Crystal & Electronic Material Precursors: Utilized in the development of fluorinated components for display technologies and dielectric materials.
• Research & Development: A valuable tool in academic and industrial labs for exploring new fluorocarbon chemistry and material science applications.
