Agropyrene Chemical Properties,Uses,Production
Chemical Properties
Almost colorless or pale yellowish crystals, or pale yellowish liquid. Poorly soluble in alcohol, miscible with essential oils and most perfume chemicals. Very unstable under UV-light or plain daylight. Oxidizes easily, and turns darker yellow. Peculiar sweet-medicinal odor, reminiscent of Anise, Estragon, etc. with a herbaceousminty note, quite tenacious.
Uses
Could find some use in perfumes and flavors, if it were made commercially available. Agropyrene constitutes more than 9000 of the essential oil of Agropyrum repens (Couchgrass).
Definition
ChEBI: Capillene is a member of benzenes.
Synthesis
Agropyrene can be produced synthetically via the ketone Capillin made from Benzaldehyde plus Pentadiyne, followed by oxidation. Also from Phenylacetaldehyde plus Methylethylketone followed by dehydration.
