Ethanol vs. Isopropanol: What's the Difference?
Ethanol is a two-carbon alcohol (C2H5OH), commonly found in beverages; isopropanol is a three-carbon alcohol (C3H8O), used as a disinfectant.
Ethanol, also known as ethyl alcohol, is a primary alcohol with two carbon atoms and a characteristic intoxicating effect, widely used in alcoholic beverages. Isopropanol, or isopropyl alcohol, is a secondary alcohol with three carbon atoms, primarily used as an antiseptic and solvent.
In chemical structure, ethanol has a simple linear chain, whereas isopropanol has a branched structure. This structural difference affects their physical and chemical properties, such as boiling points and reactivity.
Ethanol is produced by fermentation of sugars by yeast, making it a key component in wine, beer, and spirits. Isopropanol is synthesized through chemical processes, typically by hydrating propene.
In terms of usage, ethanol is utilized in the food and beverage industry, as well as a biofuel. Isopropanol is used in cleaning agents, disinfectants, and in the manufacture of certain chemicals.
When it comes to safety, ethanol is safe for consumption in regulated amounts, whereas isopropanol is toxic if ingested and is used for external applications only.

(organic compound) The aliphatic alcohol 2-propanol; isopropyl alcohol
(organic compound) A simple aliphatic alcohol formally derived from ethane by replacing one hydrogen atom with a hydroxyl group: CH3-CH2-OH.
Alcohol used as antifreeze or a solvent
Specifically, this alcohol as a fuel.
The organic compound C2H5.OH, the common alcohol which is the intoxicating agent in beer, wine, and other fermented and distilled liquors; called also ethyl alcohol. It is used pure or denatured as a solvent or in medicines and colognes and cleaning solutions, or mixed in gasoline as a fuel for automobiles, and as a rocket fuel (as in the V-2 rocket).
The intoxicating agent in fermented and distilled liquors; used pure or denatured as a solvent or in medicines and colognes and cleaning solutions and rocket fuel; proposed as a renewable clean-burning additive to gasoline
