Description

3,4-Difluorostyrene is a high-purity fluorinated styrene derivative, a key monomer and versatile building block in advanced organic synthesis. Its value lies in the unique reactivity of the vinyl group combined with the electronic effects of the difluoro substitution on the aromatic ring, enabling precise material engineering. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries, where it is used to create novel compounds with tailored properties.

Application

• Pharmaceutical Intermediate: A critical building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring fluorinated aromatic systems for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and pesticides, where the fluorine atoms improve lipophilicity and biological activity.
• Specialty Polymer Monomer: Serves as a monomer for producing fluorinated polymers and copolymers with unique properties such as chemical resistance, thermal stability, and modified surface characteristics.
• Liquid Crystal & OLED Materials: A key precursor in the synthesis of fluorinated components for electronic display technologies and organic light-emitting diodes (OLEDs).
• Advanced Material Research: Employed in R&D for creating novel organic frameworks, coatings, and functional materials that benefit from its specific electronic structure.
• Cross-coupling Reactions: Acts as a valuable substrate in palladium-catalyzed cross-coupling reactions (e.g., Heck, Suzuki) to construct complex, fluorinated molecular architectures.

Quality Control

Our 3,4-Difluorostyrene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and polymerization risk. Keep away from heat, sparks, and open flames. Due to its highly volatile nature, containers must be kept tightly sealed when not in use.
