Product Name:Erythrosine B
English Name:Erythrosine B
CAS No.:15905-32-5
Aliases:Erythrosin, Tetraiodofluorescein, Acid Red 87, Food Red 14
Molecular Formula:C20H8I4O5
Physical Properties:Red to dark red crystalline powder, odorless, slightly soluble in water, soluble in ethanol, propylene glycol and other organic solvents, producing a red solution with yellow-green fluorescence. Melting point approximately 303°C (decomposition), maximum absorption wavelength at 526 nm. Good stability to light and heat, with good acid resistance.
Uses:Erythrosine B is an important iodine-containing xanthene dye, commonly used for biological tissue staining (such as plant cytology staining) and fluorescence tracer analysis. In analytical chemistry, it serves as a redox indicator and is also used for coloring food, cosmetics, and pharmaceuticals. Additionally, it is employed as a photosensitizer in photochemical research for dye-sensitized solar cells.
Technical Specifications:
Assay (on dry basis) ≥ 95.0%
Melting point: 303°C (decomposition)
Maximum absorption wavelength: 526 nm (in ethanol)
Loss on drying ≤ 5.0%
Packaging: 500g/bottle
