Isopropyl alcohol is an organic compound with the molecular formula C3H8O. It is also known as isopropanol, 2-propanol, or rubbing alcohol. It is a colorless, flammable liquid with a strong odor and is soluble in water, alcohol, and ether.



The term “isopropyl” in isopropyl alcohol refers to the chemical structure of this compound. It has a three-carbon chain with a hydroxyl group attached to the middle carbon atom. The hydroxyl group is also known as an alcohol group, which gives this compound its characteristic properties.

2-propanol is called isopropyl alcohol because of its isomerism. Isomerism is a phenomenon in which two or more compounds have the same molecular formula but different structural arrangements of atoms. In the case of isopropyl alcohol, there are two possible structural arrangements of the molecule due to the presence of a carbon atom with three different groups attached to it.

One of these structural arrangements is called n-propanol, in which the three-carbon chain is linear. The other structural arrangement is called isopropanol, in which the carbon chain is branched. Isopropanol is the more common form of 2-propanol and is widely used in various applications.



Isopropyl alcohol has a wide range of uses, including:

- Disinfectant: Isopropyl alcohol is used as a disinfectant to kill bacteria, viruses, and fungi. It is commonly used in hospitals, clinics, and other healthcare settings.

- Solvent: Isopropyl alcohol is a good solvent for many substances, including oils, resins, and gums. It is used in the production of various products, including paints, coatings, and adhesives.

- Antifreeze: Isopropyl alcohol is used as an antifreeze in windshield washer fluid and other automotive applications.

- Fuel: Isopropyl alcohol is used as a fuel in alcohol burners and other applications.



Isopropyl alcohol is a versatile compound with a wide range of uses. Its name “isopropyl” refers to the structural arrangement of its molecules, which is different from the linear arrangement of n-propanol. Isopropyl alcohol is widely used as a disinfectant, solvent, antifreeze, and fuel.
