In the realm of advanced chemical intermediates, 2,5-Dimercaptoterephthalic Acid (CAS: 25906-66-5) is a compound of significant interest due to its unique structural features and broad applicability. As a specialized manufacturer and supplier in China, we are committed to providing high-purity 2,5-Dimercaptoterephthalic Acid to researchers and industrial clients worldwide. This article offers a comprehensive overview of its properties, synthesis pathways, and the advantages of sourcing it from a trusted Chinese partner.

2,5-Dimercaptoterephthalic Acid, also known by its IUPAC name 2,5-bis(sulfanyl)terephthalic acid, is characterized by a benzene ring substituted with two carboxylate (-COOH) groups at the 1 and 4 positions, and two thiol (-SH) groups at the 2 and 5 positions. This symmetrical arrangement results in a planar molecule with distinct hard (carboxylate) and soft (thiol) donor sites. These dual functionalities are the basis for its extensive use as a linker in the construction of Metal-Organic Frameworks (MOFs) and as a building block in supramolecular chemistry. Its appearance is typically a yellow powder, and it is supplied with a minimum purity of 98%.

The synthesis of 2,5-Dimercaptoterephthalic Acid often involves multi-step processes. A common and efficient route is the thiolation of dihydroxyterephthalic acid derivatives, typically carried out under inert atmosphere to prevent oxidation of the sensitive thiol groups. Other potential synthetic strategies include the cleavage of protected thioether intermediates or direct substitution of halogen atoms. As a dedicated manufacturer, we have optimized these synthesis routes to ensure high yields and exceptional purity, making it easier for you to buy a reliable product.

The applications of 2,5-Dimercaptoterephthalic Acid are diverse and continue to expand. Its primary use is as a versatile linker in MOF synthesis, contributing to the development of materials with tailored porosity for gas storage, separation, and catalysis. The thiol groups impart unique properties, such as enhanced affinity for heavy metals, making derived materials valuable for environmental remediation. Furthermore, its redox activity makes it a candidate for applications in energy storage and electrochemical sensing. For procurement managers seeking high-performance chemical intermediates, understanding these applications is key to identifying strategic sourcing partners.
