History

Until Varrentrapp obtained it in 1841, (-)-Carvone was probably not isolated as a pure compound. It was originally called carvol by Schweizer. Goldschmidt and Z?rrer identified it as a ketone related to limonene, and the structure was finally elucidated by Wagner in 1894.

Uses

(-)-Carvone (CAS NO.6485-40-1) can be used in foods such as chewing gum additives such as fragrance. And it is also the main raw material for spice to reconcile chicle and used in medicine and toothpaste, spices, etc.

Production

(-)-Carvone can be derived from the single of neutral sulfite derivatives France France, or hydrogen sulfide from the Spearmint oil. And it is derived by the d-line.
