Description

2,3,3,3-Tetrafluoro-2-[1,1,2,3,3,3-Hexafluoro-2-[1,1,2,2-Tetrafluoro-2-(Fluorosulphonyl)Ethoxy]Propoxy]Propionyl Fluoride is a highly fluorinated, reactive sulfonyl fluoride derivative, serving as a critical building block in advanced chemical synthesis. Its value lies in its unique structure, which enables the introduction of perfluorinated ether and sulfonyl fluoride functionalities into target molecules, imparting exceptional chemical and thermal stability. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries, particularly for developing novel materials and active ingredients with tailored properties.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially for compounds requiring perfluoroalkyl ether chains to modulate bioavailability and metabolic stability.
• Agrochemical Synthesis: Used to create novel herbicides, fungicides, and insecticides where the introduction of fluorine atoms enhances potency and environmental persistence.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for producing high-performance fluoropolymers with superior chemical resistance, low surface energy, and thermal stability for coatings, membranes, and elastomers.
• Surface Modification Agent: Imparts oil-, water-, and stain-repellent characteristics to textiles, papers, and other substrates.
• Lithium-Ion Battery Electrolytes: Potential component in the formulation of advanced electrolyte salts and additives to improve battery safety and performance at high voltages.
• Organic Synthesis Reagent: Acts as a versatile reagent for introducing sulfonyl fluoride groups, which are valuable in click chemistry and bioconjugation applications like SuFEx (Sulfur Fluoride Exchange) reactions.

Quality Control

Our production of 2,3,3,3-Tetrafluoro-2-[1,1,2,3,3,3-Hexafluoro-2-[1,1,2,2-Tetrafluoro-2-(Fluorosulphonyl)Ethoxy]Propoxy]Propionyl Fluoride adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including NMR, FT-IR, and GC/HPLC analysis, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting critical specifications. We support compliance with REACH and other global regulatory frameworks upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, amines, and reducing agents. Due to its nature as a strong acid/organic solvent, containers must be kept tightly sealed and constructed of compatible materials (e.g., PTFE, certain stainless steels). Recommended storage temperature is 2-8°C for long-term stability.
