Dimethyl terephthalate (DMT) is an organic compound with the molecular formula C10H10O4, commonly used as an intermediate in the production of polyesters, particularly polyethylene terephthalate (PET). This colorless crystalline solid has a sweet aroma and is primarily utilized in the textile, packaging, and plastics industries. DMT serves as a raw material for the synthesis of fibers, films, and containers, contributing to the creation of durable and lightweight materials. Its versatility in applications, along with its role in facilitating sustainable practices in material science, makes dimethyl terephthalate a significant compound in modern manufacturing processes.
