Ethyl Acetate CAS#141-78-6 Product Description
Ethyl acetate is one of the most widely recognized esters in chemistry and is known for its extensive range of industrial and laboratory applications. Structurally, esters are derived from carboxylic acids through the replacement of the acidic hydrogen atom with an alkyl or aryl group. At room temperature, ethyl acetate exists as a clear, colorless liquid with a characteristic pleasant, fruity aroma and a boiling point of approximately 77°C.
