Product Name:Eriochrome Black T
English Name:Eriochrome Black T
CAS No.:1787-61-7
Aliases:Solochrome Black T, Mordant Black 11
Molecular Formula:C20H12N3NaO7S
Physical Properties:Dark red to black lustrous powder; soluble in hot water and ethanol, slightly soluble in cold water, insoluble in most organic solvents. Melting point >300°C (decomposition). In the pH 8-10 range it appears blue and forms wine-red complexes with calcium and magnesium ions.
Uses:Used as a complexometric indicator, primarily for the determination of calcium and magnesium ions by EDTA titration. Also used as a colorimetric reagent for metal ion detection in analytical testing.
Technical Specifications:
Appearance: dark red to black lustrous powder
Assay: ≥98% (on dried basis)
Molecular weight: 461.38
Sensitivity: sharp color change from wine-red to blue in the pH 8-10 range
Solubility: readily soluble in hot water, soluble in ethanol, slightly soluble in cold water
