Product Name:Auramine O
English Name:Auramine O
CAS No.:492-80-8
Aliases:Basic Yellow 2, Pyoktanin Yellow, Auramine chloride
Molecular Formula:C17H22ClN3
Physical Properties:Yellow uniform powder. Slightly soluble in cold water, readily soluble in hot water and ethanol; aqueous solution shows bright yellow, ethanol solution shows yellow. When the aqueous solution is heated above 70°C, it decomposes to form tetramethylbenzophenone. It becomes colorless upon treatment with concentrated sulfuric acid and turns pale yellow after dilution. Low light fastness.
Uses:Used as a basic dye for dyeing acetate fiber, cotton, hemp, rayon and other fibers, as well as for coloring paper, leather, straw products, paints and inks. It can also be used to prepare lake pigments for wallpaper, colored paper, printing inks and paints.
Technical Specifications:
Purity ≥ 99%
Appearance: yellow uniform powder
Slightly soluble in cold water, readily soluble in hot water and ethanol
Melting point: about 170°C (decomposition)
Standards: conform to national standard, USP32, BP2002, CP2010
