ANTHRACENE (120-12-7, 54261-80-2, 90640-80-5)
anthracene, sodium salt, ion (1-)
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C14H10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes.
naphthalene (91-20-3, 68412-25-9)
Naphthalene is an organic compound with formula C 10H 8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings.
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.
Pentachloroethane is a non-flammable but toxic chemical compound of chlorine, hydrogen, and carbon. It is used as a solvent for oil and grease, in metal cleaning, and in the separation of coal from impurities.
