CHRYSENE (65996-93-2, 50-32-8, 218-01-9)
Chrysene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C 18H 12 that consists of four fused benzene rings. It is a natural constituent of coal tar, from which it was first isolated and characterized. It is also found in creosote at levels of 0.5-6 mg/kg.
benzanthracene · benzo(b)phenanthrene · 1,2-benzanthracene
Benz[a]anthracene or benzo[a]anthracene is a polycyclic aromatic hydrocarbon with the chemical formula C18H12. In February 2014, NASA announced a greatly upgraded database for tracking polycyclic aromatic hydrocarbons (PAHs), including benz[a]anthracene, in the universe. According to scientists, more than 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.
FLUORANTHENE (206-44-0, 76774-50-0)
Fluoranthene is a polycyclic aromatic hydrocarbon (PAH). The molecule can be viewed as the fusion of naphthalene and benzene unit connected by a five-membered ring. Although samples are often pale yellow, the compound is colorless.
1,2-Benzofluorene (30777-18-5, 238-84-6)
11H-benzo(a)fluorene · benzo(a)fluorene · chrysofluorene
Benzo[a]fluorene (IUPAC name, 11H-benzo[a]fluorene) is a polycyclic aromatic hydrocarbon (PAH). It is currently listed as a Group 3 carcinogen by the IARC.
benzo(c)phenanthrene · 3,4-benzophenanthrene
Benzo[c]phenanthrene is a polycyclic aromatic hydrocarbon with the chemical formula C18H12. It is a white solid that is soluble in nonpolar organic solvents. It is a nonplanar molecule consisting of the fusion of four fused benzene rings.
In chemistry, the organic compound triphenylene is a flat polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings. Triphenylene can be isolated from coal tar, but it is also made synthetically using benzyne chemistry, as it is a trimer of benzyne. One molecule of triphenylene has delocalized 18-π-electron systems based on a planar structure.
tetracene · rubene · 2,3-benzanthrene
Tetracene, also called naphthacene, is a polycyclic aromatic hydrocarbon. It has the appearance of a pale orange powder. Tetracene is the four-ringed member of the series of acenes, the previous one being anthracene (tricene) and the next one being pentacene.
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.
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.
INDAN (496-11-7, 56573-11-6)
Vinzons, officially the Municipality of Vinzons, is a 3rd class municipality in the province of Camarines Norte, Philippines. According to the 2015 census, it has a population of 43,485 people. The Calaguas Islands are part of Vinzons.
1-NONENE (124-11-8, 68855-57-2, 31387-92-5, 68526-55-6)
Nonene is an alkene with the molecular formula C9H18. Many structural isomers are possible, depending on the location of the C=C double bond and the branching of the other parts of the molecule. Industrially, the most important nonenes are trimers of propene.
