4-(9H-Carbazol-3-ylamino)phenol 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]
3-(4-Hydroxyanilino)carbazole in 107 ℃ in butanol sodium polysulfide solution reflux heating 24 hours, and then with sodium nitrite short time heating, steam out of butanol, through the air and add salt to make dye completely precipitated out. This indophenol is by carbazole and nitroso phenol in concentrated sulfuric acid in – 20 to 23 ℃ condensation, then reduction and have to (BIOS983, 71 -74). To cure solution is to add 3 – methyl – 4 ‘- hydroxy – 4 – aminodiphenylamine, 4, 4’ – dihydroxydiphenyl aniline and phenol, improved the performance of the dye (BIOS983, 75- 81). Note: use with C.I. leuco sulfur dye similar method, some the structure of the dyes can be converted into the leuco compound. | [Properties and Applications]
red light dark blue. In concentrated sulfuric acid for the faint blue, blue precipitation after dilution.
