sodium [6-amino-5-[(2-hydroxy-4-nitrophenyl)azo]naphthalene-1-sulphonato(3-)]hydroxychromate(1-)

Uses

Acid green 12 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

2-Amino-5-nitrophenol diazo, and 6-Aminonaphthalene-1-sulfonic acidcoupling, then use formic acid chromium processing.

Properties and Applications

blue light green. Variegated dark green powder. Soluble in water and ethanol (a green), slightly soluble in soluble fiber element. Meet strong sulfuric acid is blue light red, it will be diluted from blue to green solution. Its water solution meet 10% sodium hydroxide solution without change color. Used for wool, silk and polyamide fiber of dyeing and printing, also used in leather, paper dyeing and electrochemical aluminum color. Especially for the influential wool carpet and color.
