Product Overview of Ethyl acetate 99.5% CAS 141-78-6

Ethyl Acetate (also known as Ethyl Ethanoate, CAS: 141-78-6) is a common fast-evaporating ester solvent synthesized by esterification of ethanol and acetic acid. It is a colorless transparent liquid with a characteristic sweet fruity odor. Featuring strong solvency, low toxicity, mild odor and rapid volatilization without residue, it is one of the most widely used green organic solvents in industrial manufacturing, fine chemical synthesis and food processing fields.
