BETA-PINENE (127-91-3, 25719-60-2, 127-91-3, 18172-67-3)
terebenthene · terbenthene
beta-Pinene (β-pinene) is a monoterpene, an organic compound found in plants. It is one of the two isomers of pinene, the other being α-pinene. It is colorless liquid soluble in alcohol, but not water.
Cubane (C8H8) is a synthetic hydrocarbon molecule that consists of eight carbon atoms arranged at the corners of a cube, with one hydrogen atom attached to each carbon atom. A solid crystalline substance, cubane is one of the Platonic hydrocarbons and a member of the prismanes. It was first synthesized in 1964 by Philip Eaton and Thomas Cole.
Benzocyclobutadiene is the simplest polycyclic aromatic hydrocarbon, being composed of a benzene ring fused to a cyclobutadiene ring. It has chemical formula C8H6. Though the benzene ring is stabilized by aromaticity, the cyclobutadiene portion has a destabilizing effect.
Tricyclobutabenzene is an aromatic hydrocarbon consisting of a benzene core with three cyclobutane rings fused onto it. This compound and related compounds are studied in the laboratory because they are often display unusual conformations and because of their unusual reactivity. Tricyclobutabenzenes are isomers of radialenes and form an equilibrium with them.
Cuneane (C8H8, Pentacyclo[126.96.36.199 2,4.03,7.06,8]octane) is a saturated hydrocarbon. Its name is derived from the Latin cuneus, meaning a wedge. Cuneane may be produced from cubane by metal-ion-catalyzed σ-bond rearrangement.
[2.2.2]Propellane, formally tricyclo[2.2.2.01,4]octane is an organic compound, a member of the propellane family. It is a hydrocarbon with formula C8H12, or C2(C2H4)3. Its molecule has three rings with four carbon atoms each, sharing one C–C bond.
2-METHYLNAPHTHALENE (7419-61-6, 91-57-6)
2-methylnaphthalene, methyl-13C-labeled · 2-methylnaphthalene, lithium salt, ion(1-) · 2-methylnaphthalene, naphthalene-1-(13)C-labeled
2-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH). On February 22, 2014, NASA announced a greatly upgraded database for detecting and monitoring PAHs, including 2-methylnaphthalene, in the universe. According to NASA scientists, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.
Cadalene or cadalin (4-isopropyl-1,6-dimethylnaphthalene) is a polycyclic aromatic hydrocarbon with a chemical formula C15H18 and a cadinane skeleton. It is derived from generic sesquiterpenes, and ubiquitous in essential oils of many higher plants. Cadalene, together with retene, simonellite and ip-iHMN, is a biomarker of higher plants, which makes it useful for paleobotanic analysis of rock sediments.
