Naphthalenesulfonates are derivatives of sulfonic acid which contain a naphthalene functional unit.
A related family of compounds are the aminonaphthalenesulfonic acids.
Of commercial importance are the alkylnaphthalene sulfonates, which are used as superplasticizers in concrete.
They are produced on a large scale by condensation of naphthalenesulfonate or alkylnaphthalenesulfonates with formaldehyde.
