Rosindulin or Azocarmine G is a red dye that is mainly used in microscopy. It has no relation to carmine .

properties

Rosindulin is a dark red solid that is only sparingly soluble in water.

use

In microscopy , biological specimens are colored with Azocarmine G. Histologically , azocarmine G ( Az for short ) and aniline blue ( An ) are used as azan stains to differentiate between cells and the surrounding matrix.

Structural formula of azocarmine B

In addition to Azocarmin G, there is also Azocarmin B ( CI 50090, Acid Red 103), which has improved water solubility.

The term rosinduline also stands for the substance group of the monoamino derivatives of phenylnaphthophenazonium. Varying the position of the amino group results in a large number of chemical compounds that were thoroughly investigated by Friedrich Kehrmann .
