Description

Heptafluorobutyryl Fluoride is a highly reactive fluorinated acyl fluoride compound, serving as a critical building block for advanced materials synthesis. Its value lies in its ability to introduce the robust heptafluorobutyryl group, imparting exceptional chemical stability, hydrophobicity, and unique electronic properties to target molecules. This compound is essential for R&D and production in the pharmaceutical, agrochemical, and specialty polymer industries, where precise fluorination is required.

Application

• Pharmaceutical Intermediate: Key reagent for synthesizing fluorinated active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Used in the production of advanced, weather-resistant herbicides and pesticides with enhanced efficacy.
• Fluoropolymer Modification: Acts as a monomer or grafting agent to create specialty polymers with improved oil, chemical, and solvent resistance.
• Surface Treatment Agent: Imparts permanent hydrophobic and oleophobic properties to textiles, electronics, and membranes.
• Liquid Crystal & OLED Materials: A precursor for fluorinated compounds used in electronic display technologies.
• Analytical Chemistry: Employed as a derivatization agent in gas chromatography and mass spectrometry for sensitive detection.

Quality Control

Our Heptafluorobutyryl Fluoride is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each 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 away from incompatible materials such as strong bases, alcohols, and amines. Due to its highly volatile and hygroscopic nature, containers should be kept sealed under a dry, inert atmosphere (e.g., nitrogen) and at controlled room temperature (15-25°C) to maintain stability.
