Polycyclic Aromatic Hydrocarbon (PAHs) Standards

Applications 1-Pyrenol Acetate is an intermediate in the synthesis of 8-Nitro-1-pyrenol-d8 (N519992), which is an urinary hydroxylated metabolites used as a biomarkers of exposure of polycyclic aromatic hydrocarbons. This is the labeled analog. References Toriba, A., et al.: J. Health. Sci., 53; 631 (2007); Chae, Y.H., et al.: Cancer Res., 59, 1473 (1999); Sangaiah, R., et al.: Poly. Aro. Comp., 11, 283 (1996);

Applications 5-Methylchrysene is one of the methylated chrysenes (MeChry), as an aryl hydrocarbon receptor (AhR) agonist. Methylated chrysenes (MeChry) are important cigarette smoke constituents and 5-MeChry has been listed as possibly carcinogenic to humans. 5-Methylchrysene is a possible carcinogenic agent. 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 Amin, S., et al.: Cancer Res., 45, 6406 (1985), Blaha, L., et al.: Toxicol. Sci., 65, 43 (2002), Brack, W., et al.: Environ. Sci. Technol., 37, 3062 (2003), Andrysik, Z., et al.: Mutat. Res., 615, 87 (2007),

Applications A naturally abundant pneumotoxin, found primarily in mammalian feces providing its strong fecal odor. In lower concentrations however, the compound has a pleasent aroma, giving orange blossoms and jasmine their pleasing scent. It is often a component of commercial fragrances and perfumes. 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 Nakashima, T., et al.: Biol.

Applications 1,7-Dimethylnaphthalene is found in volatile oil of Phyllostachys violascens, Sinobambusa tootsik, Sasa subglabra and Pleioblastus kongosanensis leaf from different provenance and 1,7-dimethyl-naphthalene showed differential antioxidant activity.
