2-Butoxyethanol CAS#111-76-2

2-Butoxyethanol is a clear colorless liquid with an ether-like smell and belongs to the family of glycol ether/alkoxy alcohol. 2-Butoxyethanol is miscible in water and soluble in most organic solvents. 2-Butoxyethanol does not occur naturally. It is usually produced by reacting ethylene oxide with butyl alcohol.

2-Butoxyethanol is used as a solvent for nitrocellulose, natural and synthetic resins, soluble oils, in surface coatings, spray lacquers, enamels, varnishes, and latex paints, as an ingredient in paint thinners, quick-dry lacquers, latex paint, and strippers, varnish removers, and herbicides. It is also used in textile dyeing and printing, in the treatment of leather, in the production of plasticizers, as a stabilizer in metal cleaners and household cleaners, and in hydraulic fl uids, insecticides, herbicides, and rust removers. It is also used as an ingredient in liquid soaps, cosmetics, industrial and household cleaners, dry-cleaning compounds, and as an ingredient in silicon caulks, cutting oils, and hydraulic fluids. 2-Butoxyethanol is a fire hazard when exposed to heat, sparks, or open flames.

Product Application of 2-Butoxyethanol CAS#111-76-2

2-Butoxyethanol is a reagent in synthesising 4-butoxyethoxy-N-octadecyl-1,8-naphthalimide as a new fluorescent probe for determining proteins. It is also used as a reagent in synthesising 4-hydroxybenzaldehyde derivatives as tyrosinase inhibitors. It is used widely as a coupling solvent because of its superior coupling efficiency and excellent solvency for resins. Ethylene glycol monobutyl ether (2-Butoxyethanol) is used as a solvent for nitrocellulose, resins, oil, and grease and in dry cleaning.
