[Chemical Properties]

orange-brown powder
[Uses]

Eosin Acid C.I. No. 45380 (CAS# 15086-94-9) is a photo-senseitive organic catalyst and has been used in the photocatalytic, diastereoselective additions of 1-sulfoximidoyl-1,2-benziodoxoles to styrenes, and in the stereoselective synthesis of 2-deoxyglycosides from glycals. Dyes and metabolites.
[Definition]

ChEBI:Bromoeosin is an organobromine compound. It is functionally related to a fluorescein (lactone form).
[Preparation]

Fluorescein (C.I. Acid Yellow 73, C.I. 45350) in water or ethanol solution bromide into four bromine derivatives, And made into a free acid form..
[Biological Activity]

Eosin Y is a xanthene dye and is used for the differential staining of connective tissue and cytoplasm. In histopathologyit is applied as a counterstain after hematoxylin and before methylene blue. It is also used as a background stainthereby giving contrast to the nuclear stains.
[storage]

4°C, protect from light, stored under nitrogen
[Properties and Applications]

brilliant yellow red. Soluble in water and ethanol for blue light red, with yellow green fluorescence. In concentrated sulfuric acid to yellow, dilution after yellow red precipitation.
