What is Ethyl nitrate?

Plain description, key identifiers and synonyms

Ethyl nitrate appears as a clear colorless liquid with a pleasant odor. Prolonged exposure to fire or heat may cause vigorous decomposition and rupturing of the container. Denser than water and insoluble in water. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion.
