Polycyclic Aromatic Hydrocarbons (PAHs)

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.

Applications 1,4-Dihydroxynaphthalene is frequently used in organic synthesis as a reagent. In particular, it is used in the synthesis of a pH independent and cell permeant fluorescent dye, a hydroxyl regioisomeric 3',4'-benzorhodol, which can be used as a fluorescent chemosensor and biomarker for biological applications.
