生物活性
Eosin Y is widely applied as a photoredox catalyst in organic synthesis[1].
Eosin Y 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 is the most widely used counterstain in routine staining of histological tissue sections (erythrocytes, collagen, epithelial cells, etc.)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
