Chemical Property/Description

Yellowish-green shiny crystalline mass or sand. Soluble in cold, hot water is physical and chemical red purple, easily soluble in alcohol is red. In the case of concentrated sulfuric acid is yellowish-brown color, almost colorless after dilution. The aqueous solution combined  is an almost colorless liquid with a red precipitate.

Main Uses:
It is used to prepare Schiff reagent to detect aldehydes, and to determine some acid ions and metal ions by extraction spectrophotometry. Also used for photometric detection of Aussie, nitrite. Used as a great inhibitor in polarographic analysis. It is also used as a nuclear dye for biochemical analysis and is the strongest nuclear dye. It can stain mucilage, elastic tissue and fuchsinophilic particles. Nuclear staining of the central nervous system; Used in bacteriology to identify the bacterium tuberculosis; Schiff's reagent is formulated in analytical chemistry to test aldehydes. REDOX indicator titrated with australate.
