Uses 
Sodium 4-amino-1-naphthalenesulfonate is an important intermediate of azo dye, is widely used for the synthesis of direct dyes and reactive dyes, and as one of the antidote of nitrites and iodine poisoning. In recent years, we found that the amino and sulfonate groups of Sodium 4-amino-1-naphthalenesulfonate can well coordinate with power-supply atoms, so Sodium 4-amino-1-naphthalenesulfonate can be used as a donor of hydrogen bond, but also as the receptor of hydrogen key; therefore, Sodium 4-amino-1-naphthalenesulfonate is widely used to complex with a variety of metals (such as Fe, Zn, Cd, Ni, etc.) , and used for toxic chemical spill surveillance equipment, optic devices, synthesis of gas absorbing material and Clinical Research. Sodium 4-amino-1-naphthalenesulfonate can also be used for thermal switch, photoswitch, and information storage element material, DNA structure probe, DNA molecular light switch and other fields.
