Borneol (124-76-5, 464-43-7, 10385-78-1, 507-70-0)
isoborneol · isoborneol, (1R-endo)-isomer · isoborneol, (1S-endo)-isomer
Borneol is a bicyclic organic compound and a terpene derivative. The hydroxyl group in this compound is placed in an endo position. There are two different enantiomers of borneol.
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.
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.
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.
