Acid Red 94 Usage And Synthesis

Chemical Propertiesbordeaux-red to red-brown crystalline powder
Safety ProfileAn experimental teratogen. Experimental reproductive effects. Questionable carcinogen with experimental neoplastigenic data. When heated to decomposition it emits toxic fumes of Cl-, I-, and NazO.
Veterinary Drugs and TreatmentsRose bengal is a vital stain and stains dead epithelial cells and mucus. Full thickness loss of the corneal epithelium is not necessary (only dead cells need be present) to obtain rose bengal stain uptake. It does not stain epithelial defects and does not pass into intercellular spaces.
Rose bengal stain is most commonly employed in the detection of the presence of viral keratitis in the cat. Because feline herpes virus tends to infect one cell, moving then to an adjacent cell (causing the so called dendritic tracts in the cornea) without full thickness loss of corneal epithelium initially, rose bengal is an ideal diagnostic agent for this infection. Rose Bengal can also be used to detect damaged corneal epithelium on the dorsal cornea in early cases of keratoconjunctivitis sicca. Rose bengal stain is virucidal although no information is available relative to its use as a therapeutic agent.
Purification MethodsThis biological stain can be purified by chromatography on silica TLC using a 35:65 mix of EtOH/acetone as eluent. [Beilstein 19 II 261, 19 III/IV 2926.]
