Disodium terephthalate is an organic salt often used as a catalyst or intermediate in the manufacturing of various industrial and consumer goods, such as polyethylene terephthalate (PET) plastics, polyester fibers, and films. This compound boasts excellent thermal stability, chemical resistance, and mechanical properties, making it a top choice for high-performance applications. Additionally, it is non-toxic, non-flammable, and environmentally friendly, positioning it as an appealing alternative to other petroleum-based chemicals. In the food and pharmaceutical industries, Disodium terephthalate serves as a pH regulator and buffer. It is generally recognized as safe for use in food and drug applications by regulatory bodies like the FDA.
