Description

Pentafluoropropanoyl Bromide is a highly reactive fluorinated acyl bromide intermediate, essential for introducing the pentafluoropropanoyl functional group into target molecules. Its value lies in enabling precise fluorination, a critical step for modifying the physicochemical and biological properties of advanced materials and active pharmaceutical ingredients. This compound is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty materials industries for synthesizing novel fluorinated compounds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of fluorinated active pharmaceutical ingredients (APIs), particularly in antiviral and anticancer drug discovery.
• Agrochemical Synthesis: Used in the production of advanced fluorinated pesticides and herbicides to enhance their efficacy and environmental profile.
• Liquid Crystal & OLED Materials: Serves as a precursor for fluorinated components in electronic display materials, improving stability and performance.
• Polymer Modification: Employed to introduce fluorinated side chains into polymers, imparting oil/water repellency and chemical resistance.
• Organic Synthesis Reagent: A versatile acylating agent in research laboratories for the preparation of esters, amides, and ketones under mild conditions.
• Surface Treatment Agent: Used to create low-surface-energy fluorinated coatings for textiles, electronics, and medical devices.

Quality Control

Our Pentafluoropropanoyl Bromide is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use. Keep away from strong bases and oxidizing agents.
