Description

3,5-Difluorostyrene (CAS NO 182132-57-6) is a high-value fluorinated aromatic monomer essential for advanced material synthesis. Its unique structure, featuring fluorine atoms at the meta positions of the styrene ring, imparts enhanced chemical stability, thermal resistance, and specific electronic properties to resulting polymers. This compound is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel materials and fine chemicals.

Application

• Pharmaceutical Intermediate: A key building block for synthesizing fluorinated active pharmaceutical ingredients (APIs) and drug candidates, leveraging fluorine's ability to modulate bioavailability and metabolic stability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where the difluorostyrene moiety contributes to product efficacy and environmental persistence.
• Specialty Polymer Monomer: Serves as a critical monomer for creating high-performance polymers, including fluorinated polyolefins, resins, and coatings with superior chemical resistance, low surface energy, and enhanced durability.
• Liquid Crystal & OLED Materials: Employed in the synthesis of fluorinated components for liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs) to improve electronic properties and device performance.
• Advanced Material Research: A versatile reagent in academic and industrial R&D for exploring new fluorinated compounds, polymers, and nanomaterials with tailored properties.
• Cross-coupling Reactions: Acts as a substrate in various palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) to construct complex, fluorinated biaryl and other aromatic structures.

Quality Control

Our 3,5-Difluorostyrene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) detailing all specifications are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from strong acids, oxidizing agents, and sources of ignition. Due to its light-sensitive nature and reactivity with strong acids/organic solvents, prolonged exposure to light or incompatible materials should be avoided to maintain product integrity.
