For chemical formulators, R&D scientists, and procurement managers operating within the industrial chemical landscape, a thorough understanding of product properties is fundamental to successful application and procurement. Dimethyl Terephthalate (DMT), a versatile organic compound with the CAS number 120-61-6, is one such intermediate that warrants detailed attention due to its widespread use, particularly in polyester manufacturing.

DMT, chemically identified as Dimethyl benzene-1,4-dicarboxylate, presents itself as a white solid, often in flake or pellet form. Its melting point typically ranges around 140°C, transforming into a distillable, colorless liquid upon melting. This physical characteristic is significant for processing and handling within manufacturing environments. The compound's molecular formula, C10H10O4, and a molecular weight of 194.18 g/mol, are standard specifications that formulators refer to when calculating reaction stoichiometries.

From a chemical properties perspective, DMT exhibits limited solubility in water (approximately 0.0493 g/L at 20°C) but demonstrates good solubility in organic solvents like ether and chloroform, and is slightly soluble in ethanol. This solubility profile is crucial for formulators designing reaction media or purification processes. Its stability under normal storage conditions, as recommended to be below +30°C, also contributes to its ease of use as a raw material.

Understanding these properties allows formulators to predict how DMT will behave in various chemical processes. For instance, its melting point and boiling point (around 288°C) are key considerations when designing esterification or transesterification reactions, such as those involved in PET synthesis. The density of DMT, around 1.29 g/cm³, is also a practical piece of information for material handling and volumetric calculations.

For procurement professionals, knowing these specifications is essential when comparing offerings from different suppliers and ensuring the material meets the requirements for their intended applications. A high-quality manufacturer will provide comprehensive documentation, including Safety Data Sheets (SDS) and Certificates of Analysis (CoA), detailing these critical properties. When you purchase DMT, especially in bulk, confirming these specifications with your supplier is a vital step to guarantee product performance and avoid costly errors.

The market for chemical intermediates like DMT is competitive, and understanding pricing structures is part of the procurement process. Inquiring about the current price for DMT from reliable Chinese manufacturers can lead to significant cost savings for large-volume buyers.
