Thymol, a compound with CAS number 89-83-8, possesses a fascinating chemical profile that underpins its widespread utility. This article explores the chemistry of Thymol, from its molecular structure to its key physical properties and how these characteristics enable its diverse applications.

Thymol is a naturally occurring monoterpene phenol. Its molecular formula is C10H14O, and its molecular weight is approximately 150.22 g/mol. Structurally, it is an isomer of carvacrol, featuring a hydroxyl group on a phenyl ring, with an isopropyl group and a methyl group attached. Specifically, it is 2-isopropyl-5-methylphenol. This specific arrangement of functional groups is responsible for its characteristic pungent, herbaceous aroma and its phenolic properties, which include its antiseptic and antioxidant capabilities.

Physically, Thymol typically presents as a white crystalline powder or white crystals. Its melting point usually falls within the range of 48-51°C, making it a solid at room temperature but easily melted for incorporation into liquid formulations. The boiling point is around 232°C, and its density is approximately 0.965 g/mL at 25°C. Thymol is known to be sparingly soluble in water but readily soluble in organic solvents such as alcohol, ether, and chloroform. This solubility profile is critical for its use in various extraction and formulation processes.

The phenolic hydroxyl group in Thymol is weakly acidic, contributing to its ability to act as an antioxidant by scavenging free radicals. This same functional group, along with its lipophilic nature conferred by the alkyl substituents, allows Thymol to interact with microbial cell membranes, disrupting their function and leading to cell death. This is the basis for its extensive thymol antimicrobial uses.

When considering buying thymol crystals online, understanding these chemical properties is key. For instance, when formulating with Thymol for cosmetic or oral care applications, its solubility in ethanol or propylene glycol is often leveraged. The thymol purity 99% specification ensures that the chemical interactions within the formulation are predictable and that the compound performs as expected, whether for preservation, antioxidant activity, or its specific aroma profile.
