Eosin Y, also called C.I. 45380 [1] [2] or C.I. Acid Red 87, [2] [1] is a member of the triarylmethane dyes. It is produced from fluorescein by bromination. [3]
Eosin Y is commonly used as the red dye in red inks.
It is commonly used in histology, most notably in the H&E ( Haematoxylin and Eosin) stain. [1] Eosin Y is also widely used in the Papanicolaou stain (or Pap stain used in the Pap test) and the Romanowsky type cytologic stains. [1] [2] It is also used as a photosensitizer in organic synthesis. [4]
