| Description | Rose bengal, also known as ak-rose liq 1% or c.I. 45440, Belongs to the class of organic compounds known as xanthenes. These are polycyclic aromatic compounds containing a xanthene moiety, which consists of two benzene rings joined to each other by a pyran ring. Its sodium salt is commonly used in eye drops to stain damaged conjunctival and corneal cells and thereby identify damage to the eye. Rose bengal is a drug. Rose bengal is a moderately basic compound (based on its pKa). Rose bengal is a food colourant; no longer FDA permitted Rose Bengal (4,5,6,7-tetrachloro-2',4',5',7'-tetraiodofluorescein) is a stain. Rose bengal was first documented in 1987 (PMID: 2821977). Rose Bengal (4,5,6,7-tetrachloro-2',4',5',7'-tetraiodofluorescein) is a stain. |
