Diethyl Phthalate (DEP), identified by its CAS number 84-66-2, is an organic compound that plays a critical role in various industrial applications. Understanding its chemical profile, including its molecular structure, properties, and synthesis, is fundamental for appreciating its utility and for sourcing it effectively. As a diester of phthalic acid and ethanol, DEP's molecular formula is C12H14O4, and it possesses a molecular weight of 222.24 g/mol. These fundamental chemical characteristics dictate its behavior and applications.

Chemically, DEP is characterized as a colorless, oily liquid with a low volatility. Its physical properties, such as its solubility in organic solvents and its compatibility with various polymers, make it an excellent plasticizer and solvent. The synthesis of DEP typically involves the esterification of phthalic anhydride with ethanol. This reaction, often carried out at elevated temperatures and in the presence of a catalyst, yields DEP and water. The purity and quality of the resulting DEP are crucial for its intended applications, whether in cosmetics, pharmaceuticals, or industrial PVC production.
