CHEMICAL AND PHYSICAL PROPERTIES
Physical Description | C.i. acid green 3 appears as a dull dark green powder. Used as a dye for silk or wool and biological stains. |
---|---|
Color/Form | A dull, dark green powder or bright crystalline solid |
Melting Point | 255 °C (decomposes) |
Solubility | In 2-methoxyethanol 20 mg/mL; in ethanol 9 mg/mL |
Decomposition | When heated to decomposition it emits very toxic fumes of /sulfur and nitrogen oxides as well as sodium monoxide/. |
Other Experimental Properties | Soluble in water to a green solution which becomes brownish-yellow on addition of hydrochloric acid and blackish-green with sodium hydroxide. An excess of sodium hydroxide decolorizes the solution. |
Chemical Classes | Dyes -> Di- and Triaryl Dyes |
