Eosin dye is a synthetic fluorescent dye belonging to the xanthene class, primarily used in microscopy for cell staining. It binds to basic (alkaline) components of cells and is frequently used in histological procedures, especially in hematoxylin and eosin (H&E) staining.

Applications
Analytical Chemistry: Commonly used as a counterstain in biological tissue analysis.
Microscopy: Highlights cytoplasmic structures, collagen, and muscle fibers in bright pink or red, complementing hematoxylin which stains nuclei.
Laboratory Procedures: Used in cytology and histopathology for visual contrast in light microscopy.
