The Eugenol is an organic compound with the formula C10H12O2. The IUPAC name of this chemical is 2-methoxy-4-prop-2-enylphenol. With the CAS registry number 97-53-0, it is also named as phenol, 2-methoxy-4-(2-propen-1-yl)-. The product's categories are Antioxidant; Biochemistry. Besides, it is a clear colorless pale yellow or amber-colored liquid, which should be stored in a dark and cool place.It will be darkens and thickens on exposure to air. Also darkens with age. Eugenol may decompose on exposure to light. Insoluble in water.It reacts with strong alkalis. Eugenol is incompatible with strong oxidizers. This includes ferric chloride and potassium permanganate.
The Eugenol is used in perfumeries, flavorings, essential oils and in medicine as a local antiseptic and anesthetic. It is also a key ingredient in Indonesian kretek (clove) cigarettes. It was used in the production of isoeugenol for the manufacture of vanillin, though most vanillin is now produced from phenol or from lignin. Eugenol is attractive to males of various species of orchid bees, so it is commonly used as bait to attract and collect these bees for study. Eugenol derivatives or methoxyphenol are used in formulating insect attractants and UV absorbers, biocides, analgesics, and antiseptics. They are also used in manufacturing stabilizers and antioxidants for plastics and rubbers.

Preparation of Eugenol:
The Eugenol can be prepared by 1-allyloxy-2-methoxy-benzene. This reaction will need reagent BF3+2 CH3COOH. The reaction temperature is 68 °C.
Uses of Eugenol:
It can be used to produce 2-Methoxy-4-propyl-phenol at temperature of 20 °C. It will need reagent H2, catalyst 10 percent Pd/C and solvent ethanol with reaction time of 5 hours. The yield is about 98%.
When you are using Eugenol, please be cautious about it as the following:
It is harmful if swallowed and may cause sensitisation by inhalation and skin contact. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Besides, Eugenol is irritating to eyes, respiratory system and skin and limited evidence of a carcinogenic effect. When you are using it, wear suitable protective clothing, do not breathe gas/fumes/vapour/spray (appropriate wording to be specified by the manufacturer) and avoid contact with skin and eyes.
