Understanding Isopropyl Alcohol (IPA) CAS 67-63-0

CAS 67-63-0 Isopropanol, also known as isopropyl alcohol (IPA), is a versatile chemical compound widely used across an array of industries due to its unique chemical properties. Recognized as a secondary alcohol with the molecular formula C3H8O, isopropanol is a colorless liquid, characterized by a distinct odor and high volatility. Its ability to mix fully with water, ethanol, and chloroform underscores its utility as a solvent for both polar and non-polar substances, making it a cornerstone in many industrial, pharmaceutical, and consumer product applications.

 

a. Disinfectant: IPA isopropyl alcohol is commonly used in hospitals, laboratories, and households as a disinfectant. It is effective against a broad spectrum of microbes, including bacteria, viruses, and fungi.

b. Antiseptic: In medical settings, IPA solution is used as an antiseptic for cleaning wounds, disinfecting surgical instruments, and prepping the skin before injections.

c. Solvent: 99% IPA isopropyl alcohol is also used as a solvent in pharmaceuticals, cosmetics, and personal care products due to its ability to dissolve a wide range of substances.
