Cresol vs. Phenol: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 29, 2024
Cresol is a mixture of three isomeric compounds derived from phenol with a methyl group attached, while phenol itself is a simpler compound, often used as a precursor in the manufacture of other materials.
Key Differences
Cresol is composed of three isomers: ortho-, meta-, and para-cresol, each with a methyl group attached to the aromatic ring, differentiating it from phenol, which is a single compound without any methyl group.
In terms of chemical structure, cresols have a higher molecular weight compared to phenol due to the additional methyl group, while phenol consists of a hydroxyl group directly bonded to a benzene ring.
Cresol is used in disinfectants, resins, and as a precursor in the synthesis of other chemicals, whereas phenol is widely used in the production of plastics, explosives, and pharmaceuticals.
From a safety perspective, both cresol and phenol are toxic and corrosive, but cresol's toxicity varies slightly depending on its isomeric form, whereas phenol's toxicity is more consistent.
In industrial applications, cresol's varying isomers allow for more specialized uses compared to phenol, which is often employed in broader applications due to its simpler structure.
