Piperitone (89-81-6) |
| Hazard Information | Back Directory | [Uses]
Piperitone is a monoterpene compound that has a fresh minty camphor-like odour, and naturally occurs in extracts of commercial oil of peppermint. Piperitone is also used as a starting material in the synthesis of Thymol (T413000), a phenolic compound that is used for its antibacterial properties. | [Definition]
ChEBI: A p-menthane monoterpenoid that is cyclohex-2-en-1-one substituted by a methyl group at position 3 and an isopropyl group at position 6. | [Production Methods]
Piperitone is produced:
by isolation from Japanese Mint oil (dextro-Piperitone),
by isolation from Eucalyptus dives oil (laevo-Piperitone),
by hydrogenation of Diosphenol,
by reduction of 5-Methyl-2-iso-propylanisole with Sodium in liquid Ammonia.
laevo-Piperitone can also be produced from laevo-beta-Pinene via l-Limonene, by hydrogenation to /-Carvomenthene, and via 4 further intermediate steps to Piperitone.
| [General Description]
This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG | [in vivo]
The insecticidal activity of crude essential oil extracted from Cymbopogon schoenanthus and of its main constituent, Piperitone, is assessed on different developmental stages of Callosobruchus maculatus (C. maculatus). Piperitone is toxic to C. maculatus adults with a LC50 value of 1.6 μL/L. Piperitone inhibits the development of newly laid eggs and of neonate larvae, but is less toxic than the crude extract to individuals developing inside the seeds. Piperitone shows the strongest ovicidal activity. All the eggs were aborted at 6.7 μL/L. Piperitone (10 μM) kills all the neonate larvae[1]. | Animal Model: | Fifty pairs of C. maculatus adults[1] | | Dosage: | 6.7, 10, 16.7 or 33.3 μL/L | | Administration: | 24 hours | | Result: | Piperiton was more toxic than crude oil because the LC50 recorded was 1.6 μL/L for Piperitone vs. 2.7 μL/L for the crude oil.
