Cas no 4282-31-9 (thiophene-2,5-dicarboxylic acid)
Thiophene-2,5-dicarboxylic acid is a heterocyclic dicarboxylic acid derivative with the molecular formula C6H4O4S. This compound serves as a versatile building block in organic synthesis, particularly in the development of conjugated polymers, coordination polymers, and metal-organic frameworks (MOFs) due to its rigid thiophene backbone and bifunctional carboxylate groups. Its high thermal stability and ability to form strong coordination bonds with metal ions make it valuable for applications in materials science, including optoelectronics and catalysis. The compound's structural rigidity and electronic properties also contribute to its utility in designing advanced functional materials with tailored properties.
