Diethyl Oxalate

Ethyl oxalate appears as a colorless liquid. Slightly denser than water and insoluble in water. Hence sinks in water. May irritate skin and mucous membranes; may be mildly toxic by ingestion; may emit irritating fumes in a fire. Vapors are much heavier than air. Used as a solvent for plastics and in the manufacture of perfumes and pharmaceuticals. — CAMEO Chemicals
