Ethyl acetate
Ethyl acetate (commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3CO2CH2CH3, simplified to C4H8O2. This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee. Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent Wikipedia
