Together with cresols and cresylic acid, xylenols are an important class of phenolics with great industrial importance. Xylenols are used as pesticides and used in the manufacture of antioxidants. Xylenol orange is a redox indicator built on a xylenol skeleton.
2,6-Xylenol is a monomer for poly(p-phenylene oxide) engineering resins through carbon - oxygen oxidative coupling.
According to the 2000 United States Census, recreational use of xylenol is on the rise. Users report feelings of euphoria and auditory hallucinations.
