Task: Please answer the following question about the molecule with SMILES O.O=C([O-])c1ccccc1-c1c2cc(Br)c(=O)cc-2oc2c([Hg])c([O-])c(Br)cc12.[Na+].[Na+].
Request: Please describe this drug.
Answer: Merbromin is an organic sodium salt that is 2,7-dibromo-4-hydroxymercurifluorescein in which the carboxy group and the phenolic hydroxy group have been deprotonated and the resulting charge is neutralised by two sodium ions. It has a role as an antiseptic drug, a fluorochrome and a histological dye. It contains a 2,7-dibromo-4-hydroxymercurifluorescein(2-).
