Description

2,2,3,3,4,4,5,5,5-Nonafluoro-1-Pentanol is a high-value fluorinated alcohol characterized by its unique combination of a polar hydroxyl group and a highly fluorinated alkyl chain. This structure imparts exceptional properties, including high chemical and thermal stability, low surface energy, and hydrophobic/oleophobic characteristics, making it a critical intermediate for advanced materials. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing novel compounds with enhanced performance profiles.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated moieties to improve metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key building block for advanced herbicides, pesticides, and fungicides, where the fluorine atoms enhance biological activity and environmental persistence.
• Fluorinated Surfactants & Polymers: Acts as a monomer or modifier for creating specialty polymers, coatings, and surfactants with superior oil, water, and stain repellency.
• Electronics & Semiconductor Industry: Employed in the formulation of specialty cleaning agents, etching solutions, and coatings for electronic components due to its chemical inertness.
• Liquid Crystal & Display Technology: Utilized as a component in fluorinated liquid crystal mixtures for high-performance displays.
• Chemical Research & Development: A valuable reagent for introducing perfluoropentyl groups into target molecules in academic and industrial R&D settings.
