Basic Red 2 Chemical Properties,Uses,Production
Chemical Properties
Dark red to violet powder
Uses
In forensics to visualize details of cyanoacrylate-fumed friction ridges of human digits.
Preparation
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.
Definition
A red dye that flu- oresces when exposed to selected wavelengths of light.
Application
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.
Purification Methods
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
