Product Name:Eosin Y disodium salt
English Name:Eosin Y disodium salt
CAS No.:17372-87-1
Aliases:Eosin Y, Eosin Yellowish, Tetrabromofluorescein disodium salt, Water-soluble Eosin
Molecular Formula:C20H6Br4Na2O5
Physical Properties:Red or orange-red crystalline powder, readily soluble in water, slightly soluble in ethanol, insoluble in ether. The aqueous solution exhibits red fluorescence with maximum absorption at approximately 515-518 nm. The dry powder is stable but should be stored in a well-sealed container protected from light.
Uses:Primarily used in biological histology staining, serving as the core dye in hematoxylin-eosin staining to color cytoplasm, collagen fibers, and red blood cells red. It is also utilized as an adsorption indicator in analytical chemistry, as well as for fluorescence microscopy observations and preparation of laboratory pH indicators.
Technical Specifications:
Appearance: red to dark red crystalline powder
Assay (on dry basis): ≥85%
Loss on drying: ≤12%
Solubility: soluble in water (1 g/10 mL), forming a clear solution with red fluorescence
Arsenic content: ≤0.001%
