Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: O=C(ON1C(=O)CCC1=O)c1cc(Cl)c2c(c1Cl)C1(OC2=O)c2cc(Cl)c(O)c(Cl)c2Oc2c1cc(Cl)c(O)c2Cl
Constraint: Answer the question with complete sentences.
Result: The molecule is a fluorescein compound having chlorine substituents in the 2'-, 4-, 4'-, 5'-, 7- and 7'-positions and a succinimidyloxycarbonyl substituent at the 6-position. It has a role as a fluorochrome. It derives from a fluorescein.
