HPLC Method for Analysis of Guaiacol on Primesep 100 Column

Chromatogram

Description

Guaiacol is an organic compound with the chemical formula C 7 H 8 O 2 . It is a naturally occurring substance derived from guaiacum or wood creosote and it is known for its characteristic smoky odor. It can be naturally found in guaiacum wood, creosote, and certain plants or produced synthetically through the methylation of catechol or other methods. Guaiacol appears as a colorless to pale yellow aromatic oil. It is used in various foods as a smoky flavoring. Medically, it has been used in expectorants and antiseptics. Guaiacol derivatives are also used in the pharmaceutical industry. It also serves as a precursor for the synthesis of other chemicals, such as vanillin. It is a phenolic compound, specifically a methoxyphenol. It has a molecular structure consisting of a benzene ring with methoxy (-OCH3) and hydroxyl (-OH) groups attached.
