Rose oxide racemic Usage And Synthesis


Chemical Properties

Rose Oxide occurs in small quantities, mainly as the levorotatory cis form, in essential oils (e.g., Bulgarian rose oil and geranium oil). Commercial synthetic products are either optically active or inactive mixtures of the cis- and trans-isomers. Their sensory properties depend on the starting material and the method of synthesis.They are colorless liquids with a strong odor reminiscent of geranium and rose oil.

Chemical Properties

Tetrahydro-4-methyl-2-(2-methylpropen-1-yl)pyran has a powerful distinctive geranium top note.

Taste threshold values

Taste characteristics at 20 ppm: green, vegetative and herbal with a citrus nuance.
