Biological Activity
osin Y disodium is widely applied as a photoredox catalyst in organic synthesis[1].
Eosin Y disodium finds application in cell staining, as a pH indicator, as an indicator in the analytical halide determination by Fajans and as a dye pigment, e.g. in lip sticks[1].
Eosin Y disodium is the most widely used counterstain in routine staining of histological tissue sections (erythrocytes, collagen, epithelial cells, etc.)[2].
