Xanthene (9H-xanthene, 10H-9-oxaanthracene) is the organic compound with the formula CH2[C6H42O. 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. [4]
Dyes that contain a xanthene core include
bikaverin,
fluorescein,
eosins, and
rhodamines. 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.
