Benzo[a]pyrene (6699-27-0, 34505-58-3, 50-32-8, 42299-33-2)  
3,4 Benzpyrene  ·  3,4 Benzopyrene  ·  3,4-Benzopyrene
Benzo[a]pyrene is a polycyclic aromatic hydrocarbon and the result of incomplete combustion of organic matter at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F). The ubiquitous compound can be found in coal tar, tobacco smoke and many foods, especially grilled meats. The substance with the formula C20H12 is one of the benzopyrenes, formed by a benzene ring fused to pyrene.
Dibenz[a,h]anthracene (53-70-3)  
1,2,5,6-dibenzanthracene, ion(1+)  ·  1,2,5,6-dibenzanthracene  ·  dibenz(a,h)anthracene
Dibenz[a,h]anthracene is an organic compound with the chemical formula C22H14. It is a polycyclic aromatic hydrocarbon made of five fused benzene rings. It is a fused five ringed, cyclopenta, PAHs compound which is common as a pollutant of smoke and oils.
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.
Benz[a]anthracene (56-55-3)  
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.
Benzo[k]fluoranthene (207-08-9)  
Benzo[k]fluoranthene is an organic compound with the chemical formula C20H12. Classified as a polycyclic aromatic hydrocarbon (PAH), it is a colourless solid that is poorly soluble in most solvents. Impure samples can appear off white.
Benzo[b]fluoranthene (205-99-2)  
Benz[e]acephenanthrylene is an organic compound with the chemical formula C20H12. It is a polycyclic aromatic hydrocarbon (PAH) made of four benzene rings around a 5-membered ring. On February 22, 2014, NASA announced a greatly upgraded database for detecting and monitoring polycyclic aromatic hydrocarbons (PAHs), including benz[e]acephenanthrylene (as benzo[b]fluoranthene, a synonym), in the universe.
Indeno[1,2,3-cd]pyrene (193-39-5)  
Benzo[rst]pentaphene (189-55-9)  
benzo(rst)pentaphene  ·  3,4-9,10-dibenzopyrene  ·  dibenzo(a,i)pyrene
Dibenzopyrenes are a group of high molecular weight polycyclic aromatic hydrocarbons with the molecular formula C24H14. There are five isomers of dibenzopyrene which differ by the arrangement of aromatic rings: dibenzo[a,e]pyrene, dibenzo[a,h]pyrene, dibenzo[a,i]pyrene, dibenzo[a,l]pyrene, and dibenzo[e,l]pyrene. Dibenzopyrenes have been recognized for their suspected human carcinogenicity.
DMBA (57-97-6)  
7,12 Dimethylbenzanthracene  ·  7,12-Dimethylbenzanthracene  ·  9,10-Dimethyl-1,2-benzanthracene
7,12-Dimethylbenz[a]anthracene (DMBA) is an immunosuppressor and a powerful organ-specific laboratory carcinogen. DMBA is widely used in many research laboratories studying cancer. DMBA serves as a tumor initiator.
Benzo[j]fluoranthene (205-82-3)  
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.
Dibenzo[b,def]chrysene (189-64-0)  
Dibenzo[a,l]pyrene (191-30-0)  
Ba 51-090462  ·  dibenzo(def,p)chrysene  ·  1,2,3,4-dibenzopyrene
Dibenzo[a,e]pyrene (192-65-4)  
naphtho(1,2,3,4-def)chrysene  ·  DB(a,e)P  ·  1,2,4,5-dibenzopyrene
7H-Dibenzo[c,g]carbazole (194-59-2)  
Vat yellow 4 (128-66-5)  
7,14-Dibenzpyrenequinone is a yellow synthetic anthraquinone vat dye, known as Vat Yellow 4. It is a bright yellow solid. This dye is used mostly as a dye for textiles and paper.
