Thymol is a naturally occurring monoterpenoid phenol found in essential oils of aromatic plants such as thyme and oregano. It has the molecular formula C₁₀H₁₄O and generally appears as colorless crystals or a white crystalline powder with a distinctive thyme-like aroma. Its chemical structure contains a phenolic hydroxyl group attached to an aromatic ring which contributes to its characteristic chemical and biological behavior. Thymol is recognized particularly for its antimicrobial and antifungal activity and is constantly studied for its interactions with microbial cell membranes. Commercially, it can also be produced through the alkylation of m-cresol with propylene.

Thymol is the crystalline form of thymol, a natural aromatic compound primarily obtained from thyme oil and other essential oils. They are widely known for their antiseptic, antimicrobial and flavoring properties.
Thymol is chemically known as 2-isopropyl-5-methylphenol. It is a phenolic compound related structurally to cymene. It has the molecular formula C₁₀H₁₄O and is valuable in laboratory research because of its antimicrobial and antifungal properties.
Thymol is generally considered safe when used appropriately and at recommended concentrations in products such as household cleaners, cosmetics and food related applications. However, concentrated thymol may cause irritation, so it should be handled carefully and used according to the safety guidelines.
