Description

Vinyl Nonafluoro-1-Butanesulfonate is a high-value fluorinated sulfonate ester monomer, known for its unique combination of a reactive vinyl group and a highly fluorinated, electron-withdrawing sulfonate chain. This compound matters for its exceptional ability to impart surface-active properties, chemical resistance, and hydrophobicity when incorporated into polymers and advanced materials. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing novel surfactants, electrolytes, and functional materials.

Application

• Key Monomer for Fluorinated Polymers: Used in the synthesis of specialty fluoropolymers and ionomers with enhanced chemical and thermal stability.
• Surface Modification Agent: Imparts oil- and water-repellent (omniphobic) characteristics to textiles, coatings, and membranes.
• Electrolyte Additive for Lithium-Ion Batteries: Enhances battery performance and safety by forming a stable solid-electrolyte interphase (SEI) layer.
• Pharmaceutical & Agrochemical Intermediate: Serves as a versatile building block for introducing the perfluorobutylsulfonyl moiety into active molecules.
• Catalyst and Ligand Precursor: Used in organometallic chemistry and catalysis to create novel metal complexes.
• Research & Development: A critical reagent for academic and industrial research in materials science and organic synthesis.

Quality Control

Our Vinyl Nonafluoro-1-Butanesulfonate is manufactured under stringent quality management systems. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and GC, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 light-sensitive and should be stored away from direct light. Keep container tightly sealed to prevent moisture absorption and decomposition.
