Product Specifications
Eriochrome Black T is an organic azo dye with the chemical formula C₂₀H₁₂N₃NaO₇S and CAS Number 1787-61-7. It is commonly supplied as a dark-coloured powder and is widely used in laboratories, research facilities, educational institutions, and analytical testing environments.
Eriochrome Black T is valued for its ability to form coloured complexes with certain metal ions. One of its most common applications is as an indicator in EDTA complexometric titrations for determining water hardness, particularly through the analysis of calcium and magnesium ions. During the titration, the indicator produces a characteristic colour change that helps identify the endpoint.
Its indicator properties make Eriochrome Black T useful in analytical chemistry, water quality testing, complexometric titration procedures, and educational laboratory experiments. The appropriate grade and formulation should be selected according to the requirements of the intended application.
KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.
Safety Note: Eriochrome Black T may cause irritation if it comes into contact with the eyes, skin, or respiratory tract. Avoid inhaling dust and prevent direct contact with the substance. Handle it using appropriate personal protective equipment and follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
