Chemical Properties

green crystalline powder

Uses

Used for staining reticulocytes. Azure B is used for preparing azure eosin stains for blood smears.

Uses

Azure B is used for staining semi-thin sections of plant tissue. This dye is also useful in the NCCLS method for blood smears and Lillie's modified Nocht's method for paraffin sections.

Uses

Biological stain.

Definition

ChEBI: An organic chloride salt having 3-(dimethylamino)-7-(methylamino)phenothiazin-5-ium as the counterion. It is used in making azure eosin stains for blood smear staining and is an active metabolite of methylene blue.

Biochem/physiol Actions

Azure B is a cationic dye. It is part of the Romanowsky stain, which is used for staining of blood films. It is also used for the localization of nucleic acids and lignin.
