What is AURAMINE O?
Chemical properties
yellow powder
Chemical properties
Auramine is a yellow crystalline powder or flaky material.
The Uses of AURAMINE O
Certified for use by fluorescence microscopy in Churukian's modification of Truant's fluorescent method for acid fast bacilli on paraffin sections.
The Uses of AURAMINE O
Fluorescent stain for acid-resistant bacteria in sputum
What are the applications of Application
Auramine O is a stain used by fluorescence microscopy with a color index # of 41000
Definition
ChEBI: A hydrochloride obtained by combining 4,4'-carbonimidoylbis(N,N-dimethylaniline) with one molar equivalent of hydrogen chloride. A fluorescent stain for demonstrating acid fast organisms in a method similar to the Zieh Neelsen. It also can be used to make a fluorescent Schiff reagent.
General Description
Yellow flakes or powder.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
AURAMINE O is incompatible with strong oxidizing agents.
Hazard
Probable carcinogen.
Fire Hazard
Flash point data for AURAMINE O are not available. AURAMINE O is probably combustible.
Potential Exposure
Auramine is used industrially as a dye or dye intermediate for coloring textiles; paper, and leather. Also used as an antiseptic (a powerful antiseptic in ear and nose surgery, and treatment of gonorrhea) and fungicide. Human exposure to auramine occurs principally through skin absorption or inhalation of vapors. Low-level dermal exposure to the consumer may occur but would be limited to any migration of auramine from fabric, leather, or paper goods.
