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.
Acenaphthene is a polycyclic aromatic hydrocarbon (PAH) consisting of naphthalene with an ethylene bridge connecting positions 1 and 8. It is a colourless solid. Coal tar consists of about 0.3% of this compound.
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.
ACENAPHTHYLENE (208-96-8, 34493-60-2)
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.
Acenaphthoquinone is a quinone derived from acenaphthene. It is insoluble in water, but soluble in alcohol. It is used as an intermediate for the manufacturing of dyes, pharmaceuticals and pesticides.
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.
