Normal Butanol, often referred to as n-Butanol or simply N-Butanol, is a four-carbon alcohol with the chemical formula C4H10O. It is a flammable, colorless liquid with a slightly sweet odor. N-Butanol is an important solvent and chemical intermediate used in various industrial processes. One of its primary applications is as a solvent in the manufacturing of paints, coatings, and inks. Its moderate evaporation rate and solvency power make it suitable for dispersing pigments and resins in these products.

N-Butanol also serves as a raw material in the production of plasticizers, which are substances added to plastics to improve their flexibility and durability. Additionally, it finds use in the manufacture of various chemicals, including butyl acetate and butyl acrylate. Furthermore, N-Butanol is utilized in the pharmaceutical and cosmetic industries, where it can be found in products such as perfumes, lotions, and personal care items. Its ability to dissolve a wide range of compounds makes it a versatile ingredient in many formulations.
