dimethylphenol

Dimethylphenol, also known as xylenol, is a group of organic compounds with the chemical formula (CH3)2C6H4(OH). They are isomers, meaning they share the same chemical formula but differ in the arrangement of their atoms. Specifically, there are three common isomers of dimethylphenol: 2,3-dimethylphenol, 2,4-dimethylphenol, and 3,4-dimethylphenol. These compounds are derived from phenol by the addition of two methyl groups to the benzene ring.

Dimethylphenols are typically colorless to yellowish crystalline solids with a characteristic phenolic odor. They are sparingly soluble in water but readily soluble in organic solvents like ethanol and ether. These compounds are found naturally in coal tar and are also produced synthetically. Their properties vary slightly depending on the isomer.

Industrially, dimethylphenols serve as intermediates in the production of various chemicals. They are used in the synthesis of antioxidants, disinfectants, resins, and plastics. For instance, 3,4-dimethylphenol is a precursor for certain pesticides and pharmaceuticals. The specific applications often depend on the unique properties of each isomer. Environmental presence can occur due to industrial discharge and fossil fuel combustion.
