Description

Heptafluoro-4-Pentenoyl Fluoride is a highly reactive fluorinated building block essential for introducing perfluorinated acyl moieties into complex molecules. Its value lies in enabling the synthesis of advanced materials and specialty chemicals with enhanced thermal stability, chemical resistance, and unique surface properties. This compound is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced polymer industries for creating novel fluorinated compounds.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing fluorinated active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Used in the production of novel, high-performance fluorinated pesticides and herbicides.
• Fluoropolymer Modification: Serves as a monomer or grafting agent to impart oil, water, and chemical resistance to polymers.
• Surface Treatment Agent: Imparts low surface energy and hydrophobic/oleophobic properties to textiles, electronics, and membranes.
• Liquid Crystal & Electronic Materials: A precursor for fluorinated components in display technologies and semiconductor coatings.
• Organic Synthesis Reagent: A versatile acylating agent for introducing the heptafluoropentenoyl group in complex organic synthesis.

Quality Control

Every batch of our Heptafluoro-4-Pentenoyl Fluoride is produced and tested under a strict quality management system. We ensure high purity and lot-to-lot consistency through advanced analytical techniques including GC, NMR, and FTIR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 minimize volatility and degradation. Due to its hygroscopic and highly volatile nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use and allowed to equilibrate to room temperature before opening to prevent moisture ingress.
