Isobutanol is an important aliphatic saturated monohydric alcohol and one of the four isomers of butanol. It is a colorless and transparent liquid with a special pungent odor. It is miscible with most organic solvents such as ethanol and ether, and slightly soluble in water.

Isobutanol is mainly produced by the propylene oxo synthesis process and has a wide range of applications in chemical industry, medicine, food and other fields. During production and use, attention should be paid to fire and explosion prevention, and contact with skin and respiratory tract should be avoided to prevent irritation and damage.
