Description

Nonafluoropentanoyl Chloride is a highly reactive perfluorinated acid chloride, a key building block for introducing the perfluoropentyl moiety into target molecules. Its primary value lies in its ability to act as a versatile intermediate for synthesizing advanced fluorinated compounds with unique properties like oil, water, and stain repellency, as well as chemical and thermal stability. This compound is essential for R&D and production in the pharmaceutical, agrochemical, and specialty materials sectors, where precise fluorination is required to modify solubility, bioavailability, or surface characteristics.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and diagnostic agents where fluorination enhances metabolic stability and membrane permeability.
• Agrochemical Synthesis: Serves as a key precursor for creating novel fluorinated pesticides and herbicides with improved efficacy and environmental profile.
• Fluorinated Surfactants & Polymers: A critical monomer for producing high-performance fluorosurfactants, coatings, and polymers that provide exceptional water and oil repellency.
• Liquid Crystal & Electronic Materials: Employed in the manufacture of fluorinated liquid crystals and dielectric fluids for advanced display and electronic applications.
• Organic Synthesis Reagent: Acts as a versatile acylating agent in organic chemistry research to introduce the C5 perfluoroacyl group into amines, alcohols, and other nucleophiles.
• Surface Modification Agent: Used to functionalize material surfaces (e.g., textiles, membranes) to impart durable hydrophobic and oleophobic properties.

Quality Control

Our Nonafluoropentanoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize stability. This product is hygroscopic (moisture-sensitive) and reacts violently with water, alcohols, and strong bases. Containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation.
