Eugenol, a key component of clove oil, is a fascinating molecule with a distinct chemical structure that dictates its wide array of applications, from flavoring to pharmaceutical interventions. Understanding the Eugenol CAS 97-53-0 properties at a molecular level provides insight into its reactivity, stability, and therapeutic potential. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality Eugenol and educational resources to its clients.

Chemically, Eugenol is known as 4-allyl-2-methoxyphenol. Its molecular formula is C10H12O2, and its molecular weight is approximately 164.2 g/mol. The structure features a benzene ring substituted with a hydroxyl (-OH) group, a methoxy (-OCH3) group, and an allyl (-CH2-CH=CH2) group. The phenolic hydroxyl group is responsible for many of Eugenol's chemical behaviors, including its antioxidant activity and its ability to react with bases.

The presence of the allyl side chain contributes to Eugenol's reactivity. This double bond can undergo various addition reactions, and under certain conditions, it can isomerize to form isoeugenol, which has different aromatic qualities and chemical properties. This structural characteristic is important to consider in long-term storage and formulation stability. While Eugenol is generally stable, it is sensitive to air and light, which can lead to oxidation and degradation. Proper storage in airtight, opaque containers, as recommended by suppliers like NINGBO INNO PHARMCHEM CO.,LTD., is crucial.

Physically, Eugenol is described as a clear, pale yellow to yellow, oily liquid. It has a relatively high boiling point of 254°C and a low melting point between -12°C and -10°C, confirming its liquid state at room temperature. Its solubility in water is low, but it is miscible with most organic solvents and oils, which is advantageous for its incorporation into various formulations, including cosmetic and pharmaceutical products. This solubility profile is key to its use in applications where it needs to be dispersed evenly.

The phenolic hydroxyl group also makes Eugenol slightly acidic, with a pKa of around 9.8. This acidity allows it to form salts with strong bases, a property utilized in certain chemical syntheses and extractions. The aromatic nature of the benzene ring, combined with the electron-donating methoxy group and the phenolic hydroxyl, contributes to its antioxidant capabilities by stabilizing free radicals through resonance. This underpins its Eugenol anti-inflammatory activity and its role in protecting cells from oxidative damage.

In conclusion, the molecular architecture of Eugenol is the foundation of its utility. From its sensory properties utilized in Eugenol food flavoring agent applications to its biological functions explored in Eugenol pharmaceutical applications, each structural feature plays a critical role. By understanding these chemical and physical properties, industries can better leverage the full potential of this versatile natural compound.
