Description

Methyl blue belongs to the group of triaminotriphenylmethane dyes. Methyl blue is widely used as antiseptic dye in polychrome staining method and has applications in histological and microbiological staining solutions. Methyl blue has been used as a model to study the effect of various catalysts on photodegradation of dyes[1][2].

brown crystalline solid

ChEBI: An organic sodium salt that is the trisodium salt of 4,4'-{({4-[(4-sulfophenyl)imino]cyclohexa-2,5-dien-1-ylidene}methylene)bis[(4,1-phenylene)azanediyl]}di(benzene-1-sulfonic acid). A histological dye that can be used either on its own or part of a mixtur (aniline blue WS) for staining collagen in Masson's trichrome and Mallory's method for connective tissue.

Acid Blue 93 Use and Manufacturing

Methods of Manufacturing

After basic fuchsin and aniline are condensed, they are sulfonated with fuming sulfuric acid, neutralized with sodium carbonate, and acidified with sulfuric acid. Magenta base (100%) 370 Sulfuric acid 1512 Aniline (99%) 460 Fuming sulfuric acid (104.5%) 1016 Benzoic acid 10 Yuan Ming powder 7 Sodium carbonate (98%) 255

Uses

As a coloring; dye for cotton and silk; biological stain.

Methyl Blue is used as a stain for tissue in biological applications. It is also used to study aromatic framework ability to remove charged dyes from water. Methyl Blue can be used as a indicator with a range of (pH 9.4-14.0).
