Diethyl oxalate is an organic compound with the formula (CO₂CH₂CH₃)₂. It is the diethyl ester of oxalic acid. Diethyl oxalate is a colorless liquid. It is very similar to dimethyl oxalate but is a liquid at room temperature and has lower solubility in water. Both compounds are reagents in the synthesis of more complex compounds.^[2]
