Acid Blue 93 Usage And Synthesis

Chemical Properties

brown crystalline solid

Uses

A histology stain for collagen in tissue sections

Uses

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

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.

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.

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.
