Chemical Property/Description
Reddish brown powder, blue in water, slightly soluble in ethanol. The dye is yellowish-green in concentrated sulfuric acid and turns blue when diluted. The aqueous solution  is purple and dark purple precipitates are formed.




Main Uses:
Used for dyeing hemp, silk fabrics, paper and coloring bamboo and wood. It can also be used for the manufacture of ink and color lake and the dyeing of biological and bacterial tissues. It can be mixed with basic violac5bn and yellow dextrin in a ratio of 78:13:9 to form basic magenta blue.


For mild poisoning can be intravenous injection of methylene blue detoxification. The content test of stone powder in artificial sand and mixed sand (methylene blue method) chemical reagent acid titration analysis of pure methylene blue used as REDOX indicator, adsorption indicator and biological dyeing agent in chemical reagents; Analysis of pure methylene blue used for the determination of tin.

Reductive titrant used to precipitate perchlorate and rhenate. Determination of molybdenum by catalytic spectrophotometry. Chemical dye (alkaline dye: in addition to dyeing silk and wool, it is also used as dyeing agent for tissue sections and bacteria) Industrial grade methylene blue is used for dyeing cotton, acrylic fiber, hemp, silk, paper, and also used for coloring bamboo and wood and for making ink and color lake;

Medicine (Heavy metal salt detoxification, such as its ability to bind hemoglobin poisoning can be treated by intravenous methylene blue). Sterilization, insecticide.

Methylene blue is used in the development of new materials.
