Chemical Structure
Eriochrome cyanine R indicator (C.I. 43820)
- CAS No.: 3564-18-9
- Formula:C23H15Na3O9S
- Molecular Weight:536.39
IUPAC Name: sodium 5-(3-(3-carboxylato-4-hydroxy-5-methylphenyl)-1,1-dioxido-3H-benzo[c][1,2]oxathiol-3-yl)-3-methyl-2-oxidobenzoate
InChIKey: PHMYVLMZEKQMML-UHFFFAOYSA-K
SMILES: O=C(C1=C(O[Na])C(C)=CC(C2(C3=CC(C(O[Na])=O)=C(C(C)=C3)O)OS(=O)(C4=C2C=CC=C4)=O)=C1)O[Na]
Biological Activity: Eriochrome cyanine R indicator (C.I. 43820) is a hydroxy triphenylmethane metal complexing dye that forms colored complexes with ferric ions. Eriochrome cyanine R indicator (C.I. 43820) can serve as a nuclear/myelin stain, selectively staining nuclei through an anionic iron-dye complex that binds arginine-rich proteins via weak non-ionic forces, with iron ions rendering nuclei, myelin, and erythrocytes blue. Eriochrome cyanine R indicator (C.I. 43820) can be used as a histological staining reagent alternative to Hematoxylin (HY-N0116) for nuclear and myelin staining; it can also serve as a metal colorimetric indicator for analytical chemistry[1][2].
