Product Name:Basic Fuchsin
English Name:Basic Fuchsin
CAS No.:632-99-5
Aliases:Fuchsin, Magenta, Aniline Red, Rosaniline, Basic Violet 14, Magenta O
Molecular Formula:C20H20ClN3
Physical Properties:Yellow-green shiny crystalline blocks or sandy material. It dissolves in cold or hot water to give a reddish-purple solution, and is extremely soluble in alcohol giving a red solution. Concentrated sulfuric acid turns it yellowish-brown, and upon dilution the color almost disappears. When sodium hydroxide solution is added to its aqueous solution, a nearly colorless liquid with a red precipitate is formed.
Uses:It is used for dyeing cotton, acrylic fibers, silk, leather, etc., with good fastness on acrylic fibers. It is also used for coloring paper, feathers, straw, bamboo, wood, and for making lakes. In analytical chemistry, it is used to prepare Schiff's reagent for the detection of aldehydes, for extractive spectrophotometric determination of certain acid radical ions and metal ions, for photometric detection of bromine, nitrite and sulfur dioxide, and as a maximum suppressor in polarographic analysis.
Technical Specifications:
Purity ≥ 99%
Yellow-green shiny crystalline blocks or sandy material
Melting point: approximately 235°C (decomposition)
Soluble in water and ethanol, aqueous solution appears reddish-purple
Packaging: 25 kg/drum
