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.
1-METHYLNAPHTHALENE (90-12-0, 1321-94-4)  
1-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH). It has a cetane number of zero, and was previously used as the lower reference for cetane number. However, due to the expense and handling difficulty of 1-methylnaphthalene, it was replaced in this capacity by isocetane, with a CN of 15.
1,1,2,2-TETRABROMOETHANE (79-27-6)  
Tetrabromoethane (TBE) is a halogenated hydrocarbon, chemical formula C2H2Br4. Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms. It has an unusually high density for an organic compound, near 3 g/mL, due largely to the four bromine atoms.
FLUORENE (2299-68-5, 86-73-7)  
9H-fluorene
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.
