Chemical Structure
Erythrosine B aluminum
Synonym(s): Erythrosin extra bluish aluminum; Tetraiodofluorescein aluminum
- CAS No.: 12227-78-0
- Formula:C20H8I4O5.2/3Al
- Molecular Weight:853.88
SMILES: O=C1OC2(C3=C(OC4=C2C=C(I)C(O)=C4I)C(I)=C(O)C(I)=C3)C5=C1C=CC=C5.[2/3].[Al]
Biological Activity: Erythrosine B aluminum (Erythrosin extra bluish aluminum; Tetraiodofluorescein aluminum) is a visible red dye and insecticide with colorimetric and fluorescent properties. Erythrosine B aluminum serves as a membrane-impermeant live-cell dye for Gram-positive and Gram-negative bacteria, primarily staining dead cells with damaged plasma membranes. Erythrosine B aluminum exhibits photosensitive larvicidal toxicity against Culex pipiens quinquefasciatus larvae. Erythrosine B aluminum is used in live/dead bacterial assays in colorimetric and fluorescent measurements for low-, medium-, and high-throughput experiments, as well as in research related to mosquito-borne diseases and food coloring[1][2][3][4].
