Molecular formula :
MW :

nature : orange-red crystalline powder. It dilute alkaline solution, which was reflected light with the yellow-green fluorescence, in which light lens was orange and red. Melting point 314 ~ 316 ° C (closed tube, decomposition). Do not dissolve in water, ether, chloroform and benzene. Soluble dilute lye, ethanol and boiling acid. Merchandise is generally two sodium, also known as red fluorescence (fluorescein red; Fluorescein disodium salt). Yellow brown powder. Dissolved in water, ethanol-soluble. Fluorescent yellow from phthalic anhydride resorcinol with a total heat in the system. For paint system, also used as indicator.
