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.
2-CHLOROPHENOL (25167-80-0, 95-57-8)
o-chlorophenol · 2-monochlorophenol · o-monochlorophenol
2-Chlorophenol or ortho-chlorophenol is an organic compound, a derivative of phenol. Related compounds are used as a disinfectant agents and various pesticides. This particular compound has few other applications, but is an intermediate in the polychlorination of phenol.
NITROBENZENE (26969-40-4, 98-95-3)
Nitrobenzene is an organic compound with the chemical formula C6H5NO2. It is a water-insoluble pale yellow oil with an almond-like odor. It freezes to give greenish-yellow crystals.
2,4-Dinitrotoluene (DNT) or dinitro is an organic compound with the formula C7H6N2O4. This pale yellow crystalline solid is well known as a precursor to trinitrotoluene (TNT) but is mainly produced as a precursor to toluene diisocyanate.
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.
1-NITROPYRENE (63021-86-3, 5522-43-0)
1-Nitropyrene is a by-product of combustion and is the predominant nitrated polycyclic aromatic hydrocarbon (pyrene) emitted in a diesel engine. 1-Nitropyrene is listed as an IARC Group 2B carcinogen, indicating it is possibly carcinogenic to humans.
Tetrabromoethane (TBE) is a halogenated hydrocarbon, chemical formula C2H2Br4. Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms. It has an unusually high density for an organic compound, near 3 g/mL, due largely to the four bromine atoms.
