Description

2,2,2-Trifluoroethyl Perfluorobutylsulfonate is a high-purity fluorinated sulfonate ester, a key intermediate in advanced chemical synthesis. This compound is valued for its unique combination of strong electrophilicity and exceptional stability imparted by the perfluoroalkyl chain, making it a superior reagent for introducing sulfonate groups under demanding conditions. It is primarily sought by R&D and production chemists in the pharmaceutical, agrochemical, and specialty materials sectors for constructing complex molecules and modifying surfaces.

Application

• Pharmaceutical Intermediate: A critical building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of fluorinated drugs where it acts as an alkylating or sulfonylating agent.
• Agrochemical Synthesis: Used in creating advanced herbicides, fungicides, and insecticides, leveraging its ability to form stable sulfonate esters that enhance product efficacy and environmental profile.
• Polymer & Material Science: Serves as a monomer or modifier in the production of specialty polymers, including ion-exchange resins, fluoropolymers, and surfactants with unique surface properties.
• Lithium-Ion Battery Electrolytes: Investigated as a potential additive or co-solvent in electrolyte formulations to improve battery performance, safety, and high-voltage stability.
• Organic Synthesis Reagent: Employed as a powerful trifluoroethoxysulfonylating agent in fine chemical and academic research for constructing C-S and C-O bonds.
• Surface Modification: Used to impart hydrophobic and oleophobic characteristics to surfaces in coatings and textiles.

Quality Control

Our 2,2,2-Trifluoroethyl Perfluorobutylsulfonate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR (1H, 19F), HPLC, and Karl Fischer titration, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications and results are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong bases and oxidizing agents.
