The Uses of (+)-DIHYDROCARVONE

The dual, herbal-minty quality of this compound will add an interesting twist to mint flavors as well as to celery, caraway, dill and herbal flavors, especially intended for cough drops and oral care products. At very low levels, it will add depth to tropical flavors like lychee, guava, passion fruit and rambutan.

The Uses of (+)-DIHYDROCARVONE

The N-functionalization of dihydrocarvone forms imine derivatives, which are synthons for preparing N-heterocycles.
