2-Butanol, also known as sec-butanol or methyl ethyl carbinol, is a chemical compound with various industrial, commercial, and laboratory applications. Here are uses of 2-butanol:

1. Solvent: 2-Butanol is widely used as a solvent in the production of paints, coatings, varnishes, inks, and adhesives. It has good solubility for many organic compounds and is often preferred for its low toxicity and mild odor.
2. Chemical Intermediates: 2-Butanol serves as a precursor in the synthesis of other chemical compounds, including plasticizers, esters, ethers, and pharmaceuticals. It can undergo various chemical reactions, such as esterification and etherification, to produce a wide range of derivatives.
3. Cleaning Agent: Due to its solvent properties, 2-butanol is used as a cleaning agent in industrial and household applications. It is effective for removing oils, greases, resins, and other contaminants from surfaces, equipment, and machinery.
4. Extractant: 2-Butanol is utilized as an extractant in the production of natural and synthetic flavors and fragrances. It helps to extract and concentrate aromatic compounds from plant materials or reaction mixtures.
5. Denaturant: In the beverage industry, 2-butanol is sometimes added to denature ethyl alcohol (ethanol) to render it unfit for human consumption. This denatured alcohol is used in industrial applications, such as cleaning, disinfection, and fuel blending.
6. Plasticizer: 2-Butanol can be used as a plasticizer in the production of plastics and polymers to improve flexibility, durability, and processing properties. It helps to reduce brittleness and enhance the flow characteristics of polymer melts.
7. Laboratory Reagent: 2-Butanol is used as a solvent and reagent in various laboratory experiments and procedures, including chromatography, extraction, and synthesis. It is valued for its relatively low toxicity and compatibility with many organic compounds.
8. Fuel Additive: In certain fuel formulations, 2-butanol may be used as an octane booster or oxygenate additive to improve combustion efficiency and reduce emissions in gasoline engines.
9. Intermediate in Organic Synthesis: 2-Butanol serves as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. It can undergo various transformations, such as oxidation, reduction, and alkylation, to yield valuable organic products.

It’s important to handle 2-butanol with care, as it is flammable and can cause irritation to the skin, eyes, and respiratory tract upon contact or inhalation. Proper safety precautions should be observed when handling and using 2-butanol in industrial or laboratory settings.
