Isopulegol is a colorless, clear liquid with an odor of mint. There are four diastereomers of named isopulegol, iso-isopulegol, neo-isopulegol and neo-iso-isopulegol.
Isopulegol can be used as flavoring agent, flavoring substance, or for the cooling effect, as well as menthol. It is also used to prepare other synthetic flavoring substances; especially optically active menthol stereoisomers via catalytic hydrogenation of the double carbon-carbon bond in isopulegol. Also menthofuraan (which occurs in peppermint flowers), and the sweetener hernandulcin (which is present in the plant Lippia dulcis) may be prepared from isopulegol.
