Description

4-(Trifluoromethyl)Styrene is a high-value fluorinated aromatic monomer, distinguished by the presence of a reactive vinyl group and a strongly electron-withdrawing trifluoromethyl substituent. This unique structure makes it a critical building block for introducing fluorinated aromatic moieties into polymers and specialty chemicals, enhancing properties like chemical resistance, thermal stability, and surface characteristics. It is primarily sought after by R&D chemists and process engineers in the advanced polymer, pharmaceutical, agrochemical, and liquid crystal material sectors.

Application

• Advanced Polymer Synthesis: Key monomer for producing fluorinated polystyrene derivatives, specialty resins, and high-performance engineering plastics with improved solvent and chemical resistance.
• Pharmaceutical Intermediates: Serves as a versatile building block in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, leveraging the metabolic stability imparted by the CF3 group.
• Agrochemicals: Used in the development of novel herbicides, fungicides, and insecticides where the trifluoromethyl group enhances biological activity and environmental persistence.
• Liquid Crystal & OLED Materials: Incorporated into the core structure of liquid crystals and organic light-emitting diode (OLED) materials to tune electronic properties and improve performance.
• Surface Modifiers & Coatings: Employed to create hydrophobic, oleophobic, and low-surface-energy coatings for textiles, electronics, and optical devices.
• Specialty Adhesives & Sealants: Enhances the durability and environmental resistance of high-end adhesive formulations.

Quality Control

Our production of 4-(Trifluoromethyl)Styrene adheres to stringent quality management protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Every lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment, and 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 acids, bases, and oxidizing agents. Recommended storage temperature is 2-8°C to maximize shelf-life and inhibit premature polymerization. The container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) when not in use to maintain purity.
