Acid Blue 93 Chemical Properties,Usage,Production

Chemical Properties brown crystalline solid
Uses 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).
Uses As a coloring; dye for cotton and silk; biological stain.
Uses A histology stain for collagen in tissue sections
Definition 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.
Preparation (a) will C.I. Solvent Blue 23 (C.I. 42760) trisulfonated, and translated into salt; (b)Formaldehyde and 3-(Phenylamino)benzenesulfonic acid or 4-(Phenylamino)benzenesulfonic acid (2 Moore) condensation, and in the latter another Moore’s presence will the oxidation; (C) Diphenylamine and carbon tetrachloride condensation, and its products were.
Flammability and Explosibility Not classified
Biological Activity Methyl Blue is considered as a xenobiotic compound and has antiseptic property. It is useful in polychrome staining. Methyl blue is mostly used for staining samples in histology and microbiology. It is also useful as a model to reveal the role of catalyst in light induced degradation of dyes.
Properties and Applications bright blue. Flash blue brown powder. It is easy to dissolve in the cold water and hot water (for blue solution), soluble in ethanol is green light blue. Meet strong sulfuric acid is red brown, it will be a violet after diluted. Is mainly used to produce pure blue and black ink. Can make color which stamp-pad stamp-pad ink. Also used for silk, cotton and leather colorants, also can be used as indicator.
