What is Isopropyl Alcohol?
Isopropyl alcohol commonly referred to as Isopropanol or n-propanol or dimethylcarbinol is a colourless and flammable liquid with the formula C3H8O.
Isopropyl alcohol is widely employed in solvent applications. Isopropyl alcohol was one of the first petrochemical products to be manufactured and produced in 1920. The solvent properties of isopropyl alcohol are similar to ethyl alcohol. It is also called isopropyl solvents.

Chemical Properties of Isopropyl Alcohol – C3H8O
1. It reacts in a complex way with bromine giving mainly brominated acetones such as BrCH2COCBr3 and isopropyl bromide.
C3H7OH ➝ BrCH2COCBr3 + CH3CH(Br)CH3(isopropyl bromide)
2. It is the main ingredient in rubbing alcohol. It can decompose into acetone and hydrogen gas according to the following reaction.
C3H7OH ➝ C3H6O(acetone) + H2
Uses of Isopropyl Alcohol – C3H8O
- Used as a solvent and intermediate in the production of chemicals. In industry, it is used as a solvent for the instant manufacture of cements, primers, paints and varnishes.
- Most commonly used as a disinfectant for wiping down the surfaces of furniture and shelves in the operating room. It is effective against HBV viruses and is, therefore, used to clean blood or body fluids from the surface of equipment or furniture in the operating room.
