Description

2-Iodononafluorobutane is a high-purity perfluoroalkyl iodide, a versatile and critical building block in advanced chemical synthesis. Its unique structure, featuring a reactive iodine atom on a perfluorinated butyl chain, makes it an essential precursor for introducing fluorinated segments into target molecules. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors seeking to enhance product properties such as chemical stability, lipophilicity, and surface activity.

Application

• Pharmaceutical Intermediate: Key starting material for synthesizing fluorinated active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Used to create novel fluorinated pesticides and herbicides with improved efficacy and environmental profiles.
• Fluorinated Surfactant & Polymer Production: Serves as a monomer or chain-transfer agent in the synthesis of high-performance fluoropolymers and specialty surfactants.
• Organic Synthesis Reagent: Employed in radical reactions and nucleophilic substitutions to introduce the perfluorobutyl group into complex organic frameworks.
• Surface Modification: Used to create low-surface-energy coatings for textiles, electronics, and medical devices.
• Electrolyte Additive Research: Investigated for use in advanced battery systems to improve stability and performance.

Quality Control

Our 2-Iodononafluorobutane is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and NMR, to ensure high chemical purity and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, assay, and impurity profiles. We support compliance with global regulatory frameworks, including REACH.

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 and reducing agents. Recommended storage temperature is 2-8°C to maximize shelf life. Keep container tightly sealed when not in use to prevent moisture ingress and volatilization.
