CAS 141-78-6 Ethyl acetate (CH₃COOC₂H₅) is one of the most widely used organic solvents in the world. With a fruity, sweet odor and rapid evaporation rate, it serves industries from pharmaceutical manufacturing to nail salons, semiconductor fabs to cannabis extraction labs.
What is High-Purity 99% Ethyl Acetate Solvent?
High-purity 99% ethyl acetate (CAS 141-78-6) is stable and has low impurity content. Compared with low-purity solvents, 99% pure ethyl acetate has better stability, faster volatility and higher product quality.

Chemical Properties of ethyl acetate solvent
- It is the ester formed by the condensation of acetic acid and ethanol.
- Undergoes hydrolysis in the presence of acids or bases to regenerate acetic acid and ethanol.
- Acts as a polar aprotic solvent.
- Highly flammable; vapors can form explosive mixtures with air.

Uses of High-Purity 99% Ethyl Acetate
Ethyl acetate is a versatile organic compound. Its main applications include:
- Laboratory solvent: Used in column chromatography and thin-layer chromatography to purify chemical compounds.
- Paints and coatings: ethyl acetate liquid is used as a solvent in paints, varnishes, coatings, cleaners, and coatings.
- Cosmetics: Used in nail polish, nail polish remover, and perfumes.
- Food flavoring agent: Adds a sweet, fruity flavor to candies, baked goods, and wines.
- Decaffeine removal: Removes caffeine from coffee beans and tea leaves.
- Pharmaceuticals: Ethyl Acetate(EtOAc) is used as an extraction solvent in pharmaceutical production.
- Printing inks: Dissolves resins, adjusts viscosity, and controls drying speed.
- Textiles and materials: Used as a cleaner and solvent for nitrocellulose, greases, and films.
- Manufacturing: Ethyl Ethanoate is used in the production of smokeless gunpowder, artificial leather, films, and rayon.
Safety Tips of 99% Ethyl Acetate Solvent
Although ethyl acetate is considered a low-toxicity, safe solvent, proper handling and precautions are still crucial.
- Its flash point is approximately -4°C, and its vapor can form explosive mixtures with air; therefore, it must always be kept away from open flames and heat sources.
- Ethyl acetate chemical should only be used in well-ventilated areas to avoid inhaling high concentrations of vapor.
- Appropriate personal protective equipment, including gloves and goggles, must be worn, and protective clothing may be necessary.
- It should be stored in a cool, dry, well-ventilated, sealed container away from direct sunlight.
- In case of a spill, absorbent materials such as sand or cloth should be used; never discharge this chemical into sewers, and local environmental regulations must be strictly followed.
