Hidrocarbonetos aromáticos policíclicos (PAHs)

Applications The metabolite in soil and sugar beets of Chloridazon. References Smith, D.T., et al.: Weed Sci., 18, 260 (1970),

Applications Dibenzo[e,l]pyrene is a polycyclic aromatic hydrocarbon (PAH). It is an isomer of Dibenzo[a,l]pyrene (D416945) which is confirmed to be highly carcinogenic. Dibenzo[e,l]pyrene is also used as a standard in determination of polycyclic aromatic hydrocarbons (PAH’s). References Wei, S., et al.: J. Environ. Monitor., 13, 2568 (2011); Anderson, L., et al.: Toxicol. Appl. Pharmacol., 199, 85 (2004), Yu, Z., et al.: Cancer Res., 66, 755 (2006), Shen, J., et al.: Toxicol.

Applications Labelled analogue of Dibenzo[a,i]pyrene, a polycyclic aromatic hydrocarbon (PAH) with potent carcinogenic activity. Dibenzo[a,i]pyrene was shown to induce DNA adduction, tumorigenicity as well as Ki-ras oncogene mutations in strain A/J mouse lung. Dibenzo[a,i]pyrene has been shown to be present in cigarette smoke condensate and in automobile exhaust gas in small quantities.

Applications 9-Methylbenzo[g]chrysene is an metabolite of Dibenzo[def,p]chrysene (D416945), an well known polycyclic aromatics hydrocarbons found in hot mix asphalt paving workers and the most potent tumorigen that has been identified to date. References Xu, D.W., et al.: Org. Lett., 10, 1059 (2008);

Applications 1,7-Dimethylfluorene is a product of the selenium dehydrogenation of gibberic acid. 1,7-Dimethylfluorene is also one of the many polyaromatic hydrocarbons (PAH) that are found within lake sediments, negatively impacting zoo plankton changes in the water, as well as the ecosystems that reside there.
