'''Xanthene''' (9''H''-xanthene, 10''H''-9-oxaanthracene) is the [[organic compound]] with the formula CH<sub>2</sub>[C<sub>6</sub>H<sub>4</sub>]<sub>2</sub>O. It is a yellow solid that is soluble in common organic solvents. Xanthene itself is an obscure compound, but many of its derivatives are useful dyes.<ref name=Ull>{{Ullmann's | last1 = Gessner | first1 = Thomas | last2 = Mayer | first2 = Udo | title = Triarylmethane and Diarylmethane Dyes | year = 2000 | doi = 10.1002/14356007.a27_179}}</ref> |

'''Xanthene''' (9''H''-xanthene, 10''H''-9-oxaanthracene) is a yellow [[organic compound|organic]] [[heterocyclic compound]]. Its chemical formula is {{Carbon}}<sub>13</sub>{{Hydrogen}}<sub>10</sub>{{Oxygen}}. It is soluble in [[diethyl ether]]. Its melting point is 101-102 °C and its boiling point is 310-312 °C. Xanthene is used as a [[fungicide]] and it is also a useful intermediate in [[organic synthesis]]. |

[[Image:Rhodamine skeleton.svg|thumb|left|[[Rhodamine]]s are commercial dyes with xanthene cores.]] |
|||
⚫ | [[Dye]]s that contain a xanthene core include [[bikaverin]], [[fluorescein]], [[eosin]]s, and [[rhodamine]]s. Xanthene dyes tend to be [[fluorescent]], yellow to pink to bluish red, brilliant dyes. Many xanthene dyes can be prepared by condensation of derivates of [[phthalic anhydride]] with derivates of [[resorcinol]] or [[3-Aminophenol|3-aminophenol]]. |
