Ethyl acetate chemical and physical properties

Ethyl acetate, with the chemical formula C₄H₈O₂, is a colorless, transparent organic solvent with a pungent odor. It reacts with water to decompose and is not readily oxidized by strong oxidizing agents. This compound exists as a liquid at standard temperature and pressure, with a boiling point of approximately 77°C and a density of 0.9 g/mL. Ethyl acetate evaporates in air, is flammable, and readily forms explosive mixtures with air.
