| | Tracid Red 2bs Chemical Properties |
| | Tracid Red 2bs Usage And Synthesis |
| Chemical Properties | Dark brownish red powder. Slightly soluble in water. Deep red solution in concentrated sulfuric acid, precipitated after dilution. Slight change in color and light when stained with copper ions, no change when stained with iron ions. | | Uses | Acid red 266 is a multifunctional dye. Dyes are important tools in biological experiments. They can help researchers observe and analyze cell structures, track biomolecules, evaluate cell functions, distinguish cell types, detect biomolecules, study tissue pathology and monitor microorganisms. Their applications range from basic scientific research to clinical A wide range of diagnostics. Dyes are also widely used in traditional fields such as textile dyeing, as well as in emerging fields such as functional textile processing, food pigments and dye-sensitized solar cells. | | Preparation | 4-Chloro-2-(trifluoromethyl)benzenamme diazo, and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid in acid conditions coupled. | | Flammability and Explosibility | Not classified | | Properties and Applications | colourful red blue light. Dark brown powder, soluble in water. Soluble in strong sulfuric acid is a deep red in solution, after diluted NSW. Mainly used for nylon fabric dyeing and printing, and is suitable for direct printing polyamide, especially for the polyamide fiber of carpet dyeing, is not suitable for discharge printing.
