Polycyclic Aromatic Hydrocarbons (PAHs)

Applications 3,​5,​6-​Tribromo-​1,​2-​dihydroacenaphthylene is derived from Acenaphthene (1,2-Dihydro Acenaphthylene) (D448330), which is a polycyclic aromatic hydrocarbons as carcinogenic agents. References Hansen, B., et al.: Environ. Toxicol. Chem., 18, 772 (1999), Czub, G., et al.: Environ. Sci. Technol., 38, 2406 (2004)

Applications 3-Acenaphthenamine is an impurity of Acenaphthene (D448330), which is a polycyclic aromatic hydrocarbon as carcinogenic agent. References Hansen, B., et al.: Environ. Toxicol. Chem., 18, 772 (1999); Czub, G., et al.: Environ. Sci. Technol., 38, 2406 (2004)

Applications Fluoranthene is a commonly occurring environmental pollutant and can be classified as either a tumour initiator or a cocarcinogen in humans. Fluoranthene is widely used as an intermediate to synthesize fluorescent dyes. 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 Hecht, S., et al.: Carcinogenesis, 16, 1433 (1995); Storer, J., et al.: Arch. Dermatol., 120, 874 (1984); Ma, X., et al.: Dyes Pigments, 82, 353 (2009)

Applications 1-Nitropyrene-d9 is a labelled isotope of 1-Nitropyrene (N519950), which is the most abundant nitropolycylcic aromatic hydrocarbon found in exhaust from diesel engines with potent carcinogenic and mutagenic properties. It is also an intermediate in synthesizing 1-Aminopyrene-d9 (A629287), which is derived from Pyrene-d10 (P849002), which is labelled Pyrene. Occurs in coal tar. Also obtained by the destructive hydrogenation of hard coal. References Arce, R., et al.: J. Phys. Chem. A., 112, 10294 (2008); Winterstein, et al.: Z. Physiol. Chem., 230, 162 (1934);

Applications 1,5-Dihydroxynaphthalene has been incorportated into degradable lysine diisocyanate methylester-glycerol polyurethane foam and showed the presence of functional 1-naphthol group-dependent drug release in aqueous solution.

Applications 1-Methylnapththalene is a carcinogenic polycyclic aromatic hydrocarbon (PAH) that can be measured using 1-hydroxypyrene in urine as a biomarker. 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 Moen, B.E., et. al.: Occup. Environ. Med., 53, 692 (1996)
