2-Naphthol-6, 8-disulfonic acid, dipotassium salt is the potassium salt form of 2-naphthol substituted with two sulfonic acid groups, commonly used in dye manufacturing due to its high water solubility and reactivity.

 This compound has the molecular formula CHKOS and a molecular weight of approximately 384.48 g/mol. It consists of a naphthol ring system with a hydroxyl group (-OH) at position 2 and two sulfonate groups (-SO) at positions 6 and 8, each neutralized by a potassium ion (K). This dipotassium salt form enhances solubility in aqueous solutions, making it especially suitable for reactions in dye chemistry, particularly in the production of azo dyes for textiles, paper, and leather. It generally appears as a light-colored to tan crystalline powder. The compound is non-volatile and relatively stable under normal storage conditions, but it should be kept in a tightly sealed container in a cool, dry place. Proper protective equipment is recommended when handling, as it may cause mild skin and eye irritation in sensitive individuals.
