How is Pigment violet 23 made?
Pigment violet 23 is produced by condensing chloranil with 3-amino-N-ethylcarbazole, or more generally, by reacting an aniline compound with chloranil. This process creates the pigment's distinctive structure and colour. The method is entirely synthetic and does not use natural materials.
