Description

1-Phenyl-2H,2H-Perfluoroundecane-1,3-Dione is a specialized fluorinated diketone compound, distinguished by its unique perfluoroalkyl chain attached to a phenyl-substituted 1,3-diketone moiety. This structure imparts exceptional chemical and thermal stability, low surface energy, and hydrophobic/oleophobic properties, making it a valuable intermediate for advanced material synthesis. It is primarily utilized by R&D chemists and process engineers in the pharmaceutical, agrochemical, and high-performance materials sectors for creating novel fluorinated compounds.

Application

• Pharmaceutical Intermediate: Serves as a key building block for synthesizing fluorinated active pharmaceutical ingredients (APIs) and prodrugs, enhancing metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the development of novel fluorinated pesticides and herbicides, where the fluorine atoms contribute to improved efficacy and environmental persistence.
• Advanced Material Precursor: Acts as a monomer or cross-linking agent for creating fluorinated polymers, coatings, and resins with superior chemical resistance, low friction, and non-stick properties.
• Surface Modification Agent: Employed to impart permanent hydrophobic and oleophobic characteristics to textiles, membranes, and electronic components.
• Liquid Crystal & OLED Materials: A potential intermediate in the synthesis of fluorinated organic semiconductors and liquid crystal compounds for display technologies.
• Research & Development: A valuable tool for academic and industrial research exploring new reactions and properties of heavily fluorinated organic molecules.
