| Common Name | 5-Methyl-2-(1-methylethyl)-cyclohexanone |
|---|
| Description | 5-Methyl-2-(1-methylethyl)-cyclohexanone belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. |
