• All three isomers form the group of cymenes.
• Hydroxylation of any of these compounds followed by dehydration can lead to the aromatic p-cymene.
• Dusky-footed woodrats of California have been found to selectively place California umbellelone, cineole, and cymene.
• Spice-like flavors come from chemicals, such as sabinene, delta-3-carene, and para-cymene.
• He collaborated with Jean-Baptiste Dumas, and together they discovered the methyl " p "-cymene using phosphorus pentoxide.
• They also belong to the group of " p "-Cymene, it occurs in nature and is one of the terpenes.
• Upon chemical analysis of the essential oil, researchers determined the most abundant compounds to be 1.8-cineole, ?-pinene, and p-cymene.
• While with Hofmann he made researches on the oxidation of cymol or cymene, the hydro-carbon which Gerhardt and Cahours discovered in 1840 in the volatile oil of Roman cumin.
• Treatment of [ ( cymene ) RuCl 2 ] 2 with the chelating anionic ligand precursor TsDPENH gives ( cymene ) Ru ( TsDPEN-H ), a catalyst for asymmetric transfer hydrogenation.
• Treatment of [ ( cymene ) RuCl 2 ] 2 with the chelating anionic ligand precursor TsDPENH gives ( cymene ) Ru ( TsDPEN-H ), a catalyst for asymmetric transfer hydrogenation.
• Over 60 different compounds have been identified, with the primary ones being carvacrol and thymol ranging to over 80 %, while lesser abundant compounds include p-cymene, ?-terpinene, caryophyllene, spathulenol, germacrene-D, ?-fenchyl alcohol and ?-terpineol.
• The "'cymenes "'( " methylcumenes ", " isopropyltoluenes " ) constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with an isopropyl group (  CH ( CH 3 ) 2 ), and a methyl group (  CH 3 ) as a substituent.
• Recent comprehensive studies of chemical variability in hydrodistilled essential oils of different wild growing and cultivated populations of " T . pannonicus " from Hungary, as well as supercritical fluid extracts of various " Lamiaceae " species, confirmed that high concentrations of both thymol and p-cymene are the main chemosystematic attributes of " T . pannonicus " essential oil,.
• Further research efforts of Pluh醨 Zs . et al . on the volatile oil composition of " T . pannonicus " from nineteen different localities of Hungary, confirmed a significant essential oil polymorphism in this plant species, as twelve different chemovarieties were determined, namely : thymol, thymol / p-cymene, thymol / p-cymene / ?-terpinene, thymol / p-cymene / neral, thymol / p-cymene / ?-terpinene / ?-bisabolene, thymol / p-cymene / isoborneol / ?-terpinene, thymol / linalyl acetate / ?-terpinene / ?-cubebene, p-cymene / geraniol / linalyl acetate, linalyl acetate / geranyl acetate, germacrene-D / ?-caryophyllene, caryophyllene oxide / ?-cubebene / linalool, and germacrene-D / ?-caryophyllene / farnesol.
