Guaiacol (or guaiacol, named after guaiacol, native to Latin America), is a natural organic compound with the molecular formula of C6H4 (OH) (OCH3). This colorless aromatic oil like compound is the
main component of creosote and can be prepared from guaiac resin and pine oil. Common guaiacol is dark due to exposure to air or light. Due to the decomposition of lignin, guaiacol is contained in
the smoke produced by wood combustion. Many foods, such as roasted coffee beans, have a special odor due to the presence of guaiacol. [3] The special flavor of smoked food mainly belongs to the
effect of guaiacol and syringol. Guaiacol turns blue with ferric chloride.
purpose
Guaiacol is widely used in industry. Guaiacol is commonly used to produce various flavors such as eugenol, vanillin and synthetic musk. [7] [8] [9] guaiacol is also widely used in medicine.
It can be used to synthesize guaiacol benzenesulfonate (potassium guaiacol sulfonate), as a local anesthetic or preservative, as well as expectorant and treatment of dyspepsia. [10] Because of
its reducibility, it is often added as antioxidant in cosmetics and often used together with synergist and metal ion chelating agent. Guaiacol is also used as a dye because it reacts with oxygen
to produce a dark color. Guaiacol is also used as raw material for organic synthesis and reference material for analysis and determination.
