    CAS:
    Acid Black 234 is a reactive dye that is used in the textile industry. It has a hydroxy group and can be used for wastewater treatment. Acid Black 234 is not soluble in water but can be dissolved in organic solutions. It has high penetrant properties and its chemical stability depends on the pH of the solution. Acid Black 234 undergoes an adsorption mechanism, which involves a reaction with chloride ions to form a complex that binds to the surface of the fabric.
    Purity:Min. 95%
