Chemical Information
FooDB Name2-Ethyl-1-hexanol
DescriptionXi-2-ethyl-1-hexanol, also known as 2-ethylhexyl alcohol or octyl alcohol, is a member of the class of compounds known as fatty alcohols. Fatty alcohols are aliphatic alcohols consisting of a chain of a least six carbon atoms. Thus, xi-2-ethyl-1-hexanol is considered to be a fatty alcohol lipid molecule. Xi-2-ethyl-1-hexanol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Xi-2-ethyl-1-hexanol can be found in a number of food items such as tea, cereals and cereal products, fats and oils, and alcoholic beverages, which makes xi-2-ethyl-1-hexanol a potential biomarker for the consumption of these food products. Xi-2-ethyl-1-hexanol can be found primarily in feces and saliva. Xi-2-ethyl-1-hexanol exists in all eukaryotes, ranging from yeast to humans.
