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.
4,4'-dimethoxytriphenylmethyl · 4,4'-dimethoxytrityl cation
1,2-DIISOPROPYLBENZENE (577-55-9, 25321-09-9)
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.
1,2-dimethyl-4-(1-phenylethyl)benzene (58465-67-1, 6196-95-8)
PDEPE · phenyl-1-(3,4-dimethyl)phenylethane
o-fluoronitrobenzene · p-fluoronitrobenzene · 2-fluoronitrobenzene
Biphenyl (92-52-4, 68409-73-4)
diphenyl · diphenyl, 14C-labeled
Biphenyl (or diphenyl or phenylbenzene or 1,1′-biphenyl or lemonene) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl. It has a distinctively pleasant smell.
