Description:Anhydrous Methylene Blue trihydrate is gold flash gold or red flashing light of bronze powder, soluble in water, alcohol, chloroform, insoluble in ether, its solution is Blue; When concentrated sulfuric acid is yellow light green; Diluted to appear blue; When sodium hydroxide solution is added to the aqueous solution, purple or dark purple precipitation appears.
Methylene Blue trihydrate with most inorganic salt can generate complex salt. Aqueous solution is basic. Low toxicity, avoid contact with skin and eyes.
In Methylene Blue trihydrate solution of dilute sulfuric acid is added to make solution fade, if quickly adding ammonia or dew in the air can be restored.
Methylene Blue trihydrate are widely used in chemical indicator, dye, biological stain and drugs. Especially in the dyeing industry, used in the manufacture of ink, the amount of large.
