2methoxy4allylphenol

2methoxy4allylphenol, also known as eugenol, is a naturally occurring phenolic compound. It is the primary constituent of clove oil, making up 82% to 88% of the oil's composition. Eugenol is also found in smaller amounts in other plants such as nutmeg, cinnamon, basil, and bay leaf. It is a colorless to pale yellow oily liquid with a strong, spicy, clove-like odor. Its chemical formula is C10H12O2.

Eugenol has been utilized for centuries for its medicinal properties, particularly for its analgesic and antiseptic qualities. It is commonly used in dentistry as a temporary filling material and as a component in dental cements due to its ability to soothe toothaches and its antimicrobial effects. In perfumery, its distinctive aroma makes it a valuable ingredient in fragrances. It also finds application in flavorings, particularly in baked goods, candy, and beverages. Beyond these uses, eugenol has been investigated for its antioxidant, anti-inflammatory, and antimicrobial activities in scientific research. It is synthesized industrially from guaiacol.
