diethylmalonyl dichloride is an organic compound with the chemical formula C8H12Cl2O2.
Nature:
diethylmalonyl dichloride is a colorless liquid with a pungent odor at room temperature. It is readily soluble in common organic solvents such as ether and chloroform. It is sensitive to water and can react with water to form hydrogen chloride gas.
Use:
diethylmalonyl dichloride is an important intermediate in organic synthesis. It is generally used to synthesize other compounds, such as drugs, pesticides, dyes and polymer materials. It is often used as an acylating agent in organic synthesis and can be condensed with alcohols, amines and phenols.
Preparation Method:
The diethylmalonyl dichloride can be obtained by reacting diethylmalonic acid with thionyl chloride in an ice bath.
Safety Information:
diethylmalonyl dichloride is an irritant that can cause irritation when in contact with the skin and eyes. Wear appropriate protective gloves and glasses during use, and maintain good ventilation. At the same time, it should be properly stored and handled to avoid contact with strong oxidants, strong acids and strong bases. If exposed or taken by mistake, wash immediately with plenty of water and seek medical advice.
