Basic Red 2 is disclosed as colored charge-controlling agent in toners for electrophotography and as photosensitizer in solar cells. Safranine dyes are also suitable for use in photoelectric processes. Further more,they can be used as desensitizers indirect positive printing-out emulsions, for photopolymerization using visible light,a slight filters with variable optical density, and as dye components in soluble complex-forming molecules used in affinity-specific separation of nucleic acids.
| | 製造方法 | commonly known as Safranine T. Such molecular ratio of 2-Methylbenzene-1 ,4-diamine, and O-Methylaniline oxidation, the resulting condensation product of aniline and purified by precipitation segmented dye, and then converted to the chloride. | | 純化方法 | Crystallise it from *benzene/MeOH (1:1) or water. Dry it in vacuo over H2SO4. It has UV: at 520nm (H2O) and 530nm (EtOH). [Beilstein 25 H 403, 25 I 657, 25 III/IV | | Properties and Applications | bright blue light pink. Soluble in water for red, soluble in ethanol with yellow red fluorescent red. The strong sulfuric acid for green, diluted by blue to become red. The dye solution to join sodium hydroxide produce light brown red precipitate; Join the hydrochloric acid into blue purple. Used for paper making industry and color up manufacturing. Also used in acrylic, linen, silk products dyeing.
