Thymol (also known as 2-isopropyl-5-methylphenol) is a natural monoterpenoid phenol derivative of p-Cymene, extracted from thyme oil, or from Ajowan or caraway seed. It is a white crystalline substance that is soluble in alcohol and slightly soluble in water. It has a pleasant, aromatic odor reminiscent of thyme.

It is a member of the class of phenols that is phenol substituted at positions 3 and 5 by methyl and 1-propan-2-yl groups, respectively. It has a role as an antifungal agent, an antiseptic drug, a fragrance, a plant metabolite, an antioxidant, an anti-inflammatory agent, an antispasmodic drug, an anesthetic, a nematicide, a flavoring agent, a herbicide, a fungicide, a biomarker, a metabolite, a allergen, a pesticide, a molluscicide, a repellent, a bactericide, and a plant growth regulator.
