1-(Phenylamino)pseudo-mauveine: A new water soluble phenazine dye
1-(Phenylamino)pseudo-mauveine was prepared by the oxidation of 1,3,5-tris(phenylamino)benzene and p-phenylenediamine with potassium dichromate. The absorption maximum of 535 nm is shifted hypsochromically by about 20 nm compared to that for pseudo-mauvei
