Toluidine Blue O Chemical Properties,Uses,Production
Chemical Properties
Toluidine Blue O is a dark green or black-gray powder with bronze luster. It is soluble in water (3.82g/100ml), producing a blue-violet solution, slightly soluble in ethanol (0.57g/100ml) to give a blue solution, very slightly soluble in chloroform, and almost insoluble in ether.
Uses
Toluidine Blue O is a metachromatic dye suitable for a wide variety of histological staining procedures. It is used for direct dyeing and printing of wool and silk, as well as a biological stain and hemostatic agent.
Preparation
by heavy chromate salt in the presence of sodium content and deal with N1,N1-dimethylbenzene-1,4-diamine, transforming it into the content and sulfonic acid, this product then through heavy chromate salt and O-Methylaniline processing, into a unique of sulfur acid amine generation, then use heavy chromate salt and copper sulfate closed loop and oxidation, Finally,?the?zinc chloride?salt?precipitation
Definition
ChEBI: Toluidine Blue O is an organic chloride salt having 3-amino-7-(dimethylamino)-2-methylphenothiazin-5-ium (tolonium) as the counterion. It is a blue nuclear counterstain that can be used to demonstrate Nissl substance and is also useful for staining mast cell granules, both in metachromatic and orthochromatic techniques. It has a role as a fluorochrome, a histological dye and a diagnostic agent. It contains a tolonium.
