Diethyl Fumarate (DEF), identified by its CAS number 623-91-6, is a chemical compound that offers a remarkable range of functionalities across several industrial sectors. This colorless liquid ester is recognized for its utility as a plasticizer, organic synthesis intermediate, solvent, and coating agent. Understanding its intrinsic properties and the manufacturing landscape, particularly in China, provides valuable insight for industries seeking reliable chemical supply chains.

The fundamental properties of Diethyl Fumarate include its appearance as a clear, colorless liquid, with a characteristic boiling point of 218-219°C and a melting point of 1-2°C. It exhibits good solubility in common organic solvents such as ethanol and ether, while being only slightly soluble in water. These physical and chemical characteristics dictate its suitability for various applications. For instance, its solvent capabilities are leveraged in formulations for inks, adhesives, and cleaning agents, where it effectively dissolves fat-soluble compounds. This makes it a key ingredient for achieving desired product performance.

As a plasticizer, Diethyl Fumarate enhances the flexibility and workability of polymers, contributing to improved mechanical properties and longevity of plastic products. In the realm of organic synthesis, it serves as a critical intermediate, enabling the creation of complex molecules essential for pharmaceuticals and agrochemicals. The high purity levels, often exceeding 99%, achieved by leading manufacturers in China, are particularly important for these sensitive applications where contaminant control is paramount.

The manufacturing of Diethyl Fumarate typically involves the esterification of fumaric acid with ethanol.
