General Description

Disodium 7-hydroxynaphthalene-1,3-disulphonate is a chemical compound typically used in the manufacture of certain dyes and pigments. It is an organic compound that belongs to the class of naphthalenes, which are polycyclic aromatic compounds containing a naphthalene moiety. As the name indicates, this compound is made up of disodium and sulphonic acid derivatives of hydroxynaphthalene. It is highly soluble in water and might be present as a salt in its commercial form. Despite being used extensively in the colorant industry, it is always advised to handle it with precaution due to possible health hazards associated with prolonged exposure.
