Product Description:
4,4'-Thiodiphthalic anhydride is a white to off - white crystalline solid. It has a characteristic molecular structure with two phthalic anhydride units connected by a sulfur atom. It is sparingly soluble in water but soluble in some organic solvents. This compound is stable under normal conditions but may react with strong acids, bases, and oxidizing agents. It is an important intermediate in organic synthesis, especially in the production of polymers and dyes.

Application: 

4,4'-Thiodiphthalic anhydride is mainly used in the synthesis of high - performance polymers, such as polyesters and polyamides, to improve their thermal stability and mechanical properties. It is also utilized in the production of dyes and pigments, enhancing their color fastness and solubility. Additionally, it can be applied in the preparation of some special - purpose resins and coatings, providing better chemical resistance and adhesion.
