red-brown powder | [Uses]
Phloxine B acts as the sensitizers of dye-sensitized solar cells. Also, it is a fluorescein photoactive dye. Dyes and metabolites, Environmental Testing. | [Preparation]
the Resorcinol and 4,5,6,7-Tetrachloroisobenzofuran-1,3-dione condensation, get 3,4,5,6-Tetrachlorophthalic acid four bromination, and translated into sodium salt. | [Flammability and Explosibility]
Nonflammable | [Biological Activity]
Phloxine B has been demonstrated as an alternative to Gram staining. It was found to inhibit the growth of methicillin-resistant Staphylococcus aureus. Phloxine B stimulated and inhibited the channel activity of wild-type cystic fibrosis transmembrane conductance regulator (CFTR). It has antibacterial properties. Phloxine B staining can be used to distinguish between gram-positive and gram-negative bacteria. | [Properties and Applications]
brilliant pink. Soluble in water for red light blue, with weak dark green fluorescent, soluble in ethanol for blue light red, with a brick red fluorescence. In concentrated sulfuric acid for yellow, diluted into yellow red precipitation.
