Polycyclic Aromatic Hydrocarbons (PAHs)

Stability Light Sensitive Applications A PAH metabolite having a toxic effect on fish bone metabolite. Also, it is used as a marker of the carcinogenic potency of the polycyclic aromatic hydrocarbons (PAH) mixture. A genotoxic agent.

Applications 9-Fluorenone is a polycyclic aromatic ketone that has photosensitizing properties and also has the ability to undergo electrochemical polymerization. 9-Fluorenone is used in industry as an initiator in visible-light cured resin systems. 9-Fluorenone has potentially toxic effects on humans, as exposure can cause DNA mutations.

Applications Benzopyrene is a polyaromatic hydrocarbon (PAH) found in coal tar. Benzopyrene is a known carcinogen. The metabolism of Benzopyrene results in diol epoxides that react and bind to DNA forming adducts which in turns leads to mutations and eventually cancer.This compound is a contaminant of emerging concern (CECs) Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Arif, J. et al.: DNA Adducts, 127 (2010); Nair, S. et al.: Cancer Prev. Res., 2, 895 (2009); Staal, Y. et al.: Carcinogenesis, 27, 646 (2006); Mensing, T. et al.: Int. Hyg. Env. Health, 208, 197 (2005);

Applications A potent local anesthetic that is active even in acidic conditions. It is used (usually in combination with an antacid) for the relief of pain associated with peptic ulcer disease or esophagitis. References Detrain, M. et al.: Acta. Gastro-Enterol. Belg., 28, 360 (1965); Barbezat, G.O. et al.: Scand. J. Gastroenterol., 13, 321 (1978); Masuda, Y. et al.: Biochem. Pharmacol., 64, 677 (2002);

Applications 5,6-Dichloroacenaphthene is a chlorinated derivative of acenaphthene, a polycyclic aromatic hydrocarbon that has potential to act as polyploidizing agents in plants. 5,6-Dichloroacenaphthene is also used as a reagent to synthesize Corannulene, a bowl-shaped polycyclic aromatic hydrocarbon.

Am. Chem. Soc., 121, 7804 (1999)

Applications 2-Fluoronapthelene is a naphthalene which shows inhibition towards cytochrom P450 2A6 and 2A5. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Roy, K. et al.: Eur. J. Med. Chem., 44, 1941 (2009); Korhonen, L. et al.: J. Med. Chem., 48, 3808 (2005);

Applications Triphenylene (D12, 98%) (cas# 17777-56-9) is a useful research chemical.

Applications 1-Methylphenanthrene is a polycyclic aromatic hydrocarbon that has been found in particulate matter from small-scale biomass combustion from old and modern technologies and that has caused acute systemic and lung inflammation in mice after intratracheal aspiration.
