Methanol vs. Methanal: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Methanol is a simple alcohol (CH3OH) used as a solvent and fuel, while Methanal, also known as formaldehyde (CH2O), is a pungent gas used in resins and as a preservative.
Key Differences
Methanol, also known as methyl alcohol, is a chemical with the formula CH3OH. It's a light, volatile, colorless, flammable liquid with a distinctive alcoholic odor. In contrast, Methanal, better known as formaldehyde, is a simple aldehyde with the formula CH2O, recognized by its pungent, irritating smell.

Methanol is primarily used as a solvent, antifreeze, fuel, and as a denaturant for ethanol. It is also used in the production of biodiesel via transesterification reaction. On the other hand, Methanal is widely used in the manufacture of industrial resins, including adhesives used in particleboard, carpets, and insulation materials.
