Description

Trifluoroethylα-(Trifluoromethyl)Acrylate CAS NO 91520-39-7 is a highly fluorinated acrylate ester monomer, prized for its ability to impart exceptional chemical resistance, low surface energy, and thermal stability to polymeric materials. This compound is a critical building block for advanced fluoropolymers and specialty coatings where standard hydrocarbon-based materials fail. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and high-performance materials sectors for synthesizing novel compounds and functional polymers.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated motifs for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in creating advanced herbicides, fungicides, and pesticides where the introduction of fluorine atoms improves efficacy and environmental persistence.
• Fluoropolymer Production: A vital monomer for synthesizing specialty fluorinated acrylate polymers and copolymers used in high-performance coatings, sealants, and elastomers.
• Surface Modification Agents: Employed to create low-surface-energy coatings for applications in anti-fouling, anti-graffiti, and water/oil-repellent surfaces.
• Optical Materials: Incorporated into polymers for optical fibers and lenses where high transparency and environmental resistance are required.
• Lithography and Photoresists: Used in the formulation of advanced photoresists for semiconductor manufacturing due to its etching resistance.
• Adhesive and Sealant Formulations: Enhances the chemical and thermal resistance of high-end industrial adhesives.

Quality Control

Every batch of Trifluoroethylα-(Trifluoromethyl)Acrylate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the precise requirements for advanced synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for each lot and provided with shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from strong acids and incompatible organic solvents. Due to its reactive acrylate moiety, it is recommended to store under an inert atmosphere for long-term stability and to inhibit premature polymerization.
