Chemical Information
FooDB Name2-Methoxy-4-methylphenol
Description4-Methyl Guaiacol or 2-Methoxy-4-methylphenol, also known creosol, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. 4-Methyl guaiacol or Creosol is a chemical compound with the molecular formula C8H10O2. Creosol reacts with hydrogen halides to give a catechol. It is one of the components of creosote. 4-Methyl Guaiacol is a bacon, bitter, and carnation tasting compound. 4-Methyl guaiacol has been detected, but not quantified, in several different foods, such as red bell peppers, green bell peppers, orange bell peppers, corns, and pepper (c. annuum). Sources of creosol include: Coal tar, creosote wood, creosote reduction, it can be a product of vanillin using zinc powder in strong hydrochloric acid. It can be found as glycosides in green vanilla beans. It is also found in tequila. Compared with phenol, creosol is a less toxic disinfectant.
