2,3,5,6-Tetrafluoroterephthalic Acid
2,3,5,6-Tetrafluoroterephthalic Acid (CAS: 652-36-8) is a fluorinated dicarboxylic acid supplied as a white crystalline powder.
The four ring fluorines lower polarizability and increase chemical and thermal resistance while the two para carboxyl groups allow polycondensation, so the compound behaves as a fluorinated analogue of terephthalic acid.
Commercial assay is 98% with controlled inorganic content, and the product is packed in bags or drums for polymer and coordination chemistry.
• Fluorinated polyester and polyamide monomers: polycondensed to raise thermal stability and lower dielectric constant.
• Metal-organic frameworks: a rigid fluorinated linker for porous coordination materials.
• Liquid crystal polyesters: incorporated to tune transition temperatures and birefringence.
• Electronics and coatings: a precursor for fluorinated high-performance films and dielectrics.
