Description

Tetrafluoroisophthalic Acid is a high-purity fluorinated aromatic dicarboxylic acid building block, essential for synthesizing advanced materials with enhanced thermal stability and chemical resistance. Its unique structure, featuring four fluorine atoms on the isophthalic acid core, makes it a critical intermediate for creating high-performance polymers and specialty chemicals. This compound is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced polymer industries for developing novel products.

Application

• Pharmaceutical Intermediate: A key building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring fluorinated aromatic systems for improved metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where the fluorine atoms enhance biological activity and environmental persistence.
• High-Performance Polymer Monomer: Serves as a critical monomer for the synthesis of fluorinated polyamides, polyimides, and polyesters, resulting in materials with exceptional thermal stability, low dielectric constant, and chemical resistance.
• Liquid Crystal & OLED Materials: Employed in the development of fluorinated components for electronic display technologies and organic light-emitting diodes (OLEDs).
• Metal-Organic Framework (MOF) Precursor: Acts as a linker molecule in the construction of novel MOFs for gas storage, separation, and catalysis applications.
• Specialty Dyes and Pigments: Used to create fluorinated dyes with unique optical properties and enhanced fastness.

Quality Control

Our Tetrafluoroisophthalic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and batch-to-batch consistency.

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 bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Due to its acidic nature, ensure containers are kept sealed to prevent moisture absorption.
