Basic Orange 2 Appearance is flash brown red crystal or sand, melting point 118~118.5 °C. Soluble in water is yellow orange, soluble in ethanol and ethylene glycol ether, slightly soluble in acetone, insoluble in benzene. It is yellow in concentrated sulfuric acid and orange after dilution; it is orange solution in nitric acid. The aqueous solution was added to the sodium hydroxide solution to have a brown-red precipitate. The cotton fiber dyed in tannin mordant has a yellow-orange color and is more vivid under the tungsten light.

Key properties
Handling: standard dye safety precautions; avoid release to wastewater without treatment
Used for silk, wool, acrylic, tannin mordant dyeing cotton dyeing and printing, direct discharge printing. In addition, also used in leather, paper, feathers, plants and bamboo products dyeing.
5. Printing: Chrysoidine can be used for direct printing. The ground color is better with oxidized whitening, and the effect of reducing whitening is poor.
6. Other: It can be used for dyeing leather, paper, feather, grass, wood, bamboo and other products.

Use appropriate fixation (temperature/time) and cationic mordants or post-treatments; fastness varies by substrate—test on batch scale before production.
Mix only with other cationic/basic dyes. It is incompatible with anionic/direct/reactive dyes and may precipitate or lose shade if combined.
Typical loading is low because of high tinting strength—start with laboratory trial levels (e.g., 0.01–0.5% owf) and adjust by shade and substrate.
Follow standard chemical handling rules: avoid skin/eye contact, use PPE, and treat effluent per local wastewater regulations—do not release untreated dye baths to drains.
