[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
