Description

Nonafluoro-2-Butanol Fluorosulfate is a highly fluorinated organic sulfate ester, a specialized chemical intermediate of significant interest in advanced material synthesis. Its value lies in its unique molecular structure, which combines a perfluorinated alcohol moiety with a reactive fluorosulfate group, enabling its use in the creation of novel fluorinated compounds. This product is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries, where the introduction of fluorine atoms is critical for modifying compound properties such as stability, lipophilicity, and biological activity.

Application

• Fluorination Reagent: Acts as a key intermediate for introducing perfluorobutyl groups into target molecules in pharmaceutical and agrochemical research.
• Polymer Modification: Used in the synthesis of fluorinated monomers or as a surface-modifying agent to impart oil and water repellency, as well as chemical resistance, to polymers.
• Lithium-Ion Battery Electrolytes: Serves as a potential precursor or additive component for developing novel fluorinated electrolytes aimed at enhancing battery safety and performance.
• Specialty Surfactants & Coatings: A building block for creating high-performance fluorosurfactants and coatings that require exceptional stability and low surface energy.
• Organic Synthesis Intermediate: Utilized in nucleophilic substitution or elimination reactions to construct complex fluorinated architectures in fine chemical production.

Quality Control

Every batch of Nonafluoro-2-Butanol Fluorosulfate is produced and tested under a strict quality management system. We employ advanced analytical techniques including NMR, GC-MS, and HPLC to verify identity, purity, and to quantify key impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment, ensuring traceability and compliance with your internal specifications and REACH obligations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and incompatible with strong bases and fluorides; ensure the container is kept tightly sealed to exclude moisture and stored separately from incompatible materials.
