1methyl3methylphenol

1-methyl-3-methylphenol, also known as 3,5-dimethylphenol or 3,5-xylenol, is an organic compound with the chemical formula C8H10O. It is a disubstituted phenol, meaning it has two methyl groups attached to the benzene ring in addition to the hydroxyl group. Specifically, the methyl groups are located at positions 1 and 3 relative to the hydroxyl group. It is one of the three positional isomers of dimethylphenol, the others being 2,4-dimethylphenol and 2,6-dimethylphenol.

3,5-dimethylphenol is a colorless to white crystalline solid with a characteristic phenolic odor. It is sparingly soluble in water but soluble in many organic solvents such as ethanol, ether, and benzene. This compound is found naturally in small amounts in coal tar and creosote.

Industrially, 3,5-dimethylphenol is synthesized through various methods, often involving the alkylation of phenol or cresols. It finds applications as an intermediate in the production of various chemicals, including disinfectants, pesticides, and resins. Its antiseptic properties are notable, leading to its use in some pharmaceutical preparations.
