Description

5-Chlorooctafluoropentanoyl Chloride is a highly reactive perfluorinated acid chloride derivative, serving as a critical fluorinated building block in advanced chemical synthesis. Its value lies in introducing both perfluoroalkyl chains and reactive acyl chloride functionality into target molecules, enabling the creation of compounds with unique properties. This intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors, particularly for developing products requiring enhanced stability, lipophilicity, or specific surface characteristics.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) with fluorinated motifs to improve metabolic stability and membrane permeability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, pesticides, and fungicides where the perfluorinated segment can enhance weather resistance and biological activity.
• Fluorinated Surfactants & Polymers: Serves as a monomer or modifier for creating high-performance surfactants, coatings, and polymers with oil, water, and stain repellency.
• Liquid Crystal & Electronic Materials: Intermediate in the synthesis of fluorinated liquid crystals and organic electronic materials for displays and semiconductor applications.
• Organic Synthesis Reagent: Employed in Friedel-Crafts acylation and other reactions to introduce the 5-chlorooctafluoropentanoyl group into aromatic and heterocyclic systems.
• Surface Modification Agent: Used to derivatize surfaces or materials to impart low surface energy and chemical resistance.

Quality Control

Our 5-Chlorooctafluoropentanoyl Chloride is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including GC, NMR, and FTIR. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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 2-8°C (refrigerated) or as specified on the label. This material is hygroscopic (moisture-sensitive) and reacts violently with water, alcohols, and strong bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and to maintain purity.
