Description

1-Chloropentafluoro-1,3-Butadiene is a highly fluorinated and chlorinated derivative of butadiene, serving as a critical fluorinated intermediate and specialty monomer. This compound is valued for its unique reactivity and ability to introduce both fluorine and chlorine functionalities into target molecules, significantly altering their physical and chemical properties. It is primarily sought by industries involved in advanced polymer synthesis, pharmaceutical manufacturing, and the development of specialty chemicals and refrigerants.

Application

• Fluoropolymer Synthesis: Acts as a key monomer or comonomer for producing high-performance, heat- and chemical-resistant fluoropolymers and fluoroelastomers.
• Pharmaceutical Intermediates: Used in the synthesis of complex fluorinated active pharmaceutical ingredients (APIs) where fluorine substitution is required for metabolic stability or bioavailability.
• Agrochemical Manufacturing: Employed as a building block for creating novel fluorinated pesticides and herbicides with enhanced efficacy and environmental profiles.
• Specialty Refrigerants & Propellants: Serves as a precursor in the formulation of next-generation, low-global-warming-potential (GWP) fluorocarbon blends.
• Surface Modification Agents: Utilized to create hydrophobic and oleophobic coatings for textiles, electronics, and industrial materials.
• Chemical Research & Development: A valuable reagent in organic synthesis for introducing pentafluorobutadienyl and related motifs into novel chemical entities.

Quality Control

Our 1-Chloropentafluoro-1,3-Butadiene is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including Gas Chromatography (GC), Nuclear Magnetic Resonance (NMR), and Fourier-Transform Infrared Spectroscopy (FT-IR). 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, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, containers must be kept tightly sealed and upright to prevent leakage and pressure build-up. Recommended storage temperature is 2-8°C to maximize stability.
