2-BROMOPHENOL (32762-51-9, 95-56-7)
o-bromophenol · ortho-bromophenol
FLUORENE (2299-68-5, 86-73-7)
Fluorene , or 9H-fluorene, is a polycyclic aromatic hydrocarbon. It forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. It is combustible.
4-nonylphenol (104-40-5, 68081-86-7, 25154-52-3)
4-tert-nonylphenol · para-nonylphenol
Nonylphenols are a family of closely related organic compounds called alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics.
2-METHYLNAPHTHALENE (7419-61-6, 91-57-6)
2-methylnaphthalene, methyl-13C-labeled · 2-methylnaphthalene, lithium salt, ion(1-) · 2-methylnaphthalene, naphthalene-1-(13)C-labeled
2-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH). On February 22, 2014, NASA announced a greatly upgraded database for detecting and monitoring PAHs, including 2-methylnaphthalene, in the universe. According to NASA scientists, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.
ANTHRACENE (120-12-7, 54261-80-2, 90640-80-5)
anthracene, sodium salt, ion (1-)
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C14H10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes.
Cadalene or cadalin (4-isopropyl-1,6-dimethylnaphthalene) is a polycyclic aromatic hydrocarbon with a chemical formula C15H18 and a cadinane skeleton. It is derived from generic sesquiterpenes, and ubiquitous in essential oils of many higher plants. Cadalene, together with retene, simonellite and ip-iHMN, is a biomarker of higher plants, which makes it useful for paleobotanic analysis of rock sediments.
