Ethyl acetate (EtOAc CAS 141-78-6) is one of the most widely used ester solvents in the global chemical industry. It is known for its mild fruity odor, relatively low toxicity, fast evaporation rate, and strong solvency. Thanks to these properties, it is used across a range of industries, including manufacturing, pharmaceuticals, food processing, and advanced materials.
Below is a clear overview of its chemical structure, formula, key characteristics, and main industrial applications.
Properties of Ethyl Acetate (EtOAc CAS 141-78-6)
Chemical Properties
Ethyl acetate (EtOAc) belongs to the family of esters, a common class of organic compounds formed from the reaction of an alcohol and a carboxylic acid.
EtOAc chemical structure and properties
The molecular formula of ethyl acetate is C4H8O2. It consists of two carbonyl-linked groups: a methyl (from acetic acid) and an ethoxy (from ethanol). Its structure can also be written as CH3COOC2H5 or CH3−COO−CH2CH3.
This structure delivers balanced performance for industrial processing:
- Clear, colorless liquid with a characteristic sweet, fruity smell
- High solubility in alcohols, ketones, ethers, and most organic solvents
- Fast-drying, low corrosiveness, and good compatibility with resins and polymers
- Compliant with food-contact and pharmaceutical purity standards
- Recognized as a greener alternative to benzene and high-VOC solvents
