Identification
Common NameRose bengal
ClassSmall Molecule
DescriptionA xanthene dye that is fluorescein bearing bromine substituents at positions 2', 4', 5' and 7' (on the xanthene ring) and iodine substituents at position 2, 3, 4, and 5 (on the phenyl ring). The dipotassium salt is the biological stain 'rose bengal'.
