Diethyl fumarate(CAS: 623-91-6)

Diethyl fumarate is an organic compound with the chemical formula C8H12O4. It is a colorless liquid with a faint odor and is commonly used as a crosslinking agent. Diethyl fumarate has a high reactivity due to its conjugated double bond and is known for its ability to form polymers and resins. It is also used in the synthesis of other organic compounds.

Diethyl fumarate is widely used in the pharmaceutical industry for the production of drugs and as a precursor in organic synthesis. It finds applications in polymer science for creating coatings and resins. Additionally, it is used in the food industry as a stabilizer and in research for developing new materials and chemical compounds.

Diethyl fumarate is generally considered safe when handled properly, but it can be toxic if inhaled or ingested. Protective measures such as gloves, goggles, and proper ventilation are recommended. Safety standards require adherence to OSHA and EPA guidelines to ensure safe handling and disposal, minimizing exposure risks.

Diethyl fumarate should be stored in a cool, dry, and well-ventilated area away from light. It is best kept in a sealed container at a temperature below 25°C and humidity levels below 60%. Storage precautions include keeping it away from incompatible materials and ensuring it is not exposed to heat or direct sunlight to maintain stability.
