Description

Nonafluoropentanoyl Bromide is a high-purity fluorinated acyl bromide intermediate, essential for introducing the perfluoropentanoyl moiety into target molecules. Its primary value lies in enabling the synthesis of complex fluorinated compounds, which are critical for enhancing material properties like chemical resistance, thermal stability, and surface activity. This reagent is particularly needed by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel active ingredients and specialty polymers.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing fluorinated active pharmaceutical ingredients (APIs) and prodrugs.
• Agrochemical Synthesis: Used in the production of advanced, high-performance fluorinated pesticides and herbicides.
• Fluorinated Surfactant & Polymer Production: Serves as a monomer or modifier to create materials with exceptional oil, water, and stain resistance.
• Liquid Crystal & Electronic Material Precursor: Employed in the synthesis of fluorinated components for display technologies and semiconductor coatings.
• Organic Synthesis & Research Reagent: A versatile reagent in academic and industrial R&D labs for introducing perfluoroacyl groups.
• Surface Modification Agent: Used to impart low surface energy and hydrophobic/oleophobic properties to various substrates.

Quality Control

Our Nonafluoropentanoyl Bromide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, it must be kept under an inert atmosphere (e.g., nitrogen or argon) and away from moisture, bases, and oxidizing agents.
