Diethyl Terephthalate (DET), identified by CAS number 636-09-9, stands as a cornerstone in the realm of chemical intermediates, particularly for the polymer industry. As a diester derived from terephthalic acid and ethanol, its molecular formula C12H14O4 and molecular weight of 222.24 g/mol hint at its structural significance. The compound presents as a white crystalline solid, boasting a purity typically exceeding 98.0% and a melting point in the range of 42-45°C. These characteristics make it an ideal candidate for applications demanding precise chemical composition and reliable performance.

The primary utility of Diethyl Terephthalate lies in its role as a precursor for polyethylene terephthalate (PET). When integrated into PET chains, DET contributes significantly to enhanced mechanical strength and improved thermal stability. This is crucial for manufacturing durable fibers, films, and, most notably, the ubiquitous beverage bottles that shape modern packaging. For businesses looking to buy PET intermediates, understanding the quality and sourcing of DET is paramount. A consistent supply of high-purity Diethyl Terephthalate from a trusted manufacturer ensures the integrity and performance of the final polymer products.

Beyond PET, Diethyl Terephthalate finds application as a versatile plasticizer. It imparts flexibility and improves the processability of various thermoplastics, including polyvinyl chloride (PVC). Its low volatility and excellent compatibility with polymer matrices make it a preferred choice for demanding sectors like automotive interiors and construction materials. For manufacturers seeking to purchase plasticizers, the benefits of DET in enhancing material properties are substantial. When sourcing these critical additives, engaging with a reputable supplier ensures consistent quality and efficacy.

Furthermore, Diethyl Terephthalate serves as a valuable solvent in specific organic synthesis applications, particularly for reactions requiring elevated temperatures due to its high boiling point of 302°C. Its ability to participate in transesterification reactions also makes it a useful building block for synthesizing other chemical compounds. For research scientists and industrial chemists, identifying reliable sources for Diethyl Terephthalate for organic synthesis is key to efficient reaction development and scaling. Inquiring about the price and availability from established chemical manufacturers can streamline procurement processes.
