acenaphthylene, radical ion (1-)
Acenaphthylene is a polycyclic aromatic hydrocarbon. The molecule resembles naphthalene with positions 1 and 8 connected by a C2H2 unit. It is a yellow solid.
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.
1,2,3,4-Tetrahydronaphthalene (68412-24-8, 119-64-2)
Tetralin (1,2,3,4-tetrahydronaphthalene) is a hydrocarbon having the chemical formula C10H12. This molecule is similar to the naphthalene chemical structure except that one ring is saturated.
1,2-DIHYDRONAPHTHALENE (447-53-0, 29828-28-2)
Dialin (1,2-dihydronaphthalene) is a hydrocarbon with the chemical formula C10H10. It is similar to naphthalene but one ring is partially saturated.
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.
