CAS No. 541-02-6 is 2-Butoxyethanol, or ethylene glycol monobutyl ether, which is a colorless, low viscosity liquid. It has a characteristic ether-like odor and is miscible with water and common organic solvents.
2-Butoxyethanol is used as a solvent for many organic and inorganic compounds including dyes, resins, oils, waxes and paints. It is also used as a surfactant, emulsifier, and coupling agent in formulations.
2-Butoxyethanol is an important intermediate in the production of alkyd resins, glycol ethers and other compounds. It is also used in degreasers, cleaners, and metalworking fluids.
2-Butoxyethanol is a hazardous material and should be handled with care. It is classified as a skin and eye irritant and its vapors are toxic. It should be stored in tightly closed containers in a cool, dry place.
2-Butoxyethanol is also known as ethylene glycol monobutyl ether, 2-Butoxyethyl alcohol, 1-Butoxy-2-ethanol, Butyl Cellosolve, Butyl glycol, Butyl oxitol, Ethylene glycol butyl ether, and Glycol monobutyl ether.
