| | 食用 赤色 104号 Usage And Synthesis |
| 外観 | 黄赤色～赤褐色, 粉末 | | 定義 | 本品は、平成15年厚労省令第126号に示される赤色104号の(1)又はそのアルミニウムレーキ又はそのバリウムレーキである。 | | 溶解性 | 水に易溶、pH 4.5以下で不溶性。酸に不安定。 | | 用途 | 印刷インキ、化粧品原料。 | | 化粧品の成分用途 | 着色剤 | | 化学的特性 | red-brown powder | | 使用 | Phloxine B acts as the sensitizers of dye-sensitized solar cells. Also, it is a fluorescein photoactive dye. Dyes and metabolites, Environmental Testing. | | 製造方法 | 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. | | 燃焼性と爆発性 | Non flammable | | 生物活性 | 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. | | 安全性プロファイル | Poison by intravenous route. An experimental teratogen. Other experimental reproductive effects. When heated to decomposition it emits very toxic fumes of Br-, Cl-, and NazO. | | 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.
