Description

Perfluorobutyl Iodide is a high-purity fluorinated organic iodide compound, serving as a critical building block for advanced materials synthesis. Its value lies in the unique reactivity of the iodine atom and the exceptional stability imparted by the perfluorinated alkyl chain. This makes it an essential intermediate for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to incorporate fluorinated segments. It is particularly vital for creating surfactants, surface modifiers, and other performance chemicals where fluorination enhances properties like oil repellency, chemical resistance, and thermal stability.

Application

• Pharmaceutical Intermediate: Used in the synthesis of fluorinated active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Serves as a key precursor for creating fluorinated pesticides and herbicides with enhanced efficacy and environmental persistence.
• Fluorinated Surfactant & Polymer Production: A fundamental monomer for manufacturing perfluoropolyethers (PFPEs), fluorinated acrylates, and specialty surfactants.
• Surface Modification Agent: Imparts oil, water, and stain repellency to textiles, paper, and coatings.
• Electronics Industry: Used in the plasma etching and cleaning processes for semiconductor manufacturing.
• Organic Synthesis Reagent: Employed in radical reactions and as a perfluoroalkylating agent in research and development.

Quality Control

Our Perfluorobutyl Iodide is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high chemical purity and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing purity, identity, and impurity profiles. Our quality commitment ensures the material meets the exacting standards required for sensitive applications in pharmaceutical and electronic chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place away from incompatible materials such as strong bases and reducing agents. Recommended storage temperature is between 2°C and 8°C (refrigerated) to maximize shelf-life stability, though short-term storage at 15-25°C is acceptable. Keep container tightly sealed when not in use to prevent moisture ingress and volatility loss.
