Butanone, also known as methyl ethyl ketone (MEK), is a colorless, flammable liquid with a sweet odor. It is commonly used as a solvent in various industrial processes, including the production of plastics, textiles, and paints. Butanone has the chemical formula C4H8O and is classified as a ketone due to the presence of a carbonyl group. In addition to its industrial applications, butanone is also found in some household products, such as nail polish removers and adhesives. It is important to handle butanone with care, as it can be harmful if inhaled or ingested. Proper ventilation and protective equipment are recommended when using products containing this chemical.
