Naphthalenesulfonate
Class of chemical compounds
Naphthalenesulfonates
amaranth dye
amido black
congo red
suramin
trypan blue
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.[1][2]
Examples include:
- amaranth dye
- amido black
- armstrong's acid
- congo red
- Evans blue
- suramin
- trypan blue
