Fluorene (EINECS NO 201-695-5)
Fluorene, or 9H-fluorene, is a polycyclic aromatic hydrocarbon. Fluorene forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. Fluorene is combustible. Fluorene has a violet fluorescence, hence its name. For commercial purposes fluorene is obtained from coal tar,Fluorene is insoluble in water and soluble in many organic solvents.

Fluorene is widely used as material additive in biological pharmacy, chemical research, chemical synthesis fields and so on.
1)Fluorene is a precursor to other fluorene compounds; the parent species has few applications. Fluorene-9-carboxylic acid is a precursor to pharmaceuticals. 2-Aminofluorene, 3,6-bis-(dimethylamino)fluorene, and 2,7-diiodofluorene are precursors to dyes.
2) Oxidation of fluorene gives fluorenone, which is nitrated to give commercially useful derivatives.
3) 9-Fluorenylmethyl chloroformate (Fmoc chloride) is used to introduce the 9-fluorenylmethyl carbamate (Fmoc) potecting group on amines in peptide synthesis.
4) Polyfluorene polymers (where carbon 7 of one unit is linked to carbon 2 of the next one, displacing two hydrogens) are electrically conductive and electroluminescent, and have been much investigated as a luminophore in organic light-emitting diodes.
5) Cicloprofen is a NSAID 2-arylpropionic acid made from fluorene.
