Metabolite Identification
Common Name2-Exo-hydroxy-1,8-cineole
Description2-Exo-hydroxy-1,8-cineole, also known as 6-endo-hydroxycineole, belongs to the class of organic compounds known as oxanes. Oxanes are compounds containing an oxane (tetrahydropyran) ring, which is a six-member saturated aliphatic heterocycle with one oxygen atom and five carbon atoms. Thus, 2-exo-hydroxy-1,8-cineole is considered to be an isoprenoid lipid molecule. 2-Exo-hydroxy-1,8-cineole is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
