what is ethyl acetate EA(CAS 141-78-6)?
Ethyl acetate (EA) is an ester containing the functional group -COOR (a double bond between carbon and oxygen), capable of undergoing common ester reactions such as hydrolysis, amination, ester exchange, and reduction. Low toxicity with a sweet taste, it emits a pungent odor at higher concentrations. Highly volatile, it exhibits excellent solubility and rapid drying properties, making it widely used as a crucial organic chemical feedstock and industrial solvent. Classified as a Class 1 flammable substance, ethyl acetate must be stored in a cool, well-ventilated area away from ignition sources.
What is the formula of ethyl acetate?
Ethyl acetate (commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3CO 2CH 2CH 3, simplified to C 4H 8O 2.
