	Methylene blue - Wikipedia, the free encyclopedia
		Methylene Blue, methylthionine chloride or 3,7-bis(dimethylamino)phenothiazin-5-ium chloride is a chemical compound used as a dye and medication for Gram's stain, Wright's stain, and Jenner's stain and the treatment of methemoglobinemia.
		Methylene Blue is also used in aquaculture, particularly by tropical fish hobbyists, as a treatment for ich (Ichthyophthirius multifilis).
		Methylene Blue should not be confused with another histology stain methyl blue.

		Methylene chloride was first prepared in 1840 by the French chemist Henri Victor Regnault, who isolated it from a mixture of chloromethane and chlorine that had been exposed to sunlight.
		Industrially, methylene chloride is produced by reacting either methyl chloride or methane with chlorine gas at 400-500°C. At these temperatures, both methane and methyl chloride undergo a series of reactions producing progressively more chlorinated products.
		Methylene chloride is the least toxic of the simple chlorohydrocarbons, but it is not without its health risks.

		The methylene blue test is a test to determine the type of methemoglobinemia an affected person has, based on the responsiveness of blood methemoglobin to the administration of methylene blue (a dark green powder that can turn methemoglobin back into normal hemoglobin).
		Most methemoglobinemia quickly responds to IV administration of methylene blue, and can be controlled by daily doses of oral methylene blue and ascorbic acid.
		If the administration of IV methylene blue does not significantly lower blood levels of methemoglobin, then a rare form of hereditary methemoglobinemia is suspected.

		A corrin is a polyaromatic ring related to the porphyrin ring in hemoglobin, consisting of 4 pyrrole subunits, joined on opposite sides by a C-CH3 methylene link, on one side by a C-H methylene link, and with the two of the pyrroles joined directly.
		Compared to a porphyrin, it is missing a bridging methylene group between a pair of pyrroles.
		Because of the loss of the bridging methylene, they do not have a full aromatic character around the entire ring.
