sodium naphthionate 130-13-2

Sodium 1-naphthalamine-4-naphthalene sulfonate (commonly known as sodium 4-amino1-naphthalene sulfonate, referred to as sodium 1, 4-sodium) is an important azo pigment intermediate [1], which is widely used to synthesize direct dyes and reactive dyes. Meanwhile, sodium 1, 4-sodium sulfonate is also one of the antidotes to nitrite salts and iodine poisoning. In recent years found that 1, 4 acid sodium amino sulfonic group and all can very good coordination with power supply atoms, so 1, 4 acid sodium can be used as hydrogen bond donors, also can be used as a hydrogen bond acceptor, make 1, 4 are widely used in acid sodium and various metal (such as Fe, zinc, Cd, Ni, etc.) complex, toxic chemicals used for leakage monitoring equipment, optical device, gas absorption material in the synthesis and clinical medical research. Sodium 1,4 sodium can also be used in thermal switch, optical switch and information storage element materials, DNA structure probe, DNA molecular optical switch and other fields. Sodium 1-naphthalamine-4-sulfonate is often supplied in the form of 1-naphthalamine-4-sodium sulfonate tetrhydrate in the laboratory

Sodium 1-naphthalamine-4-sulfonate is one of the important azo pigment intermediates, which is widely used to synthesize direct dyes and reactive dyes, and is also one of the antidotes to nitrite salts and iodine poisoning. In recent years found that 1 - naphthylamine - 4 - sulfonic acid sodium amino sulfonic group and all can very good coordination with power supply atoms, so 1 - naphthylamine - 4 - sulfonic acid sodium can be used as hydrogen bond donors, also can be used as a hydrogen bond acceptor, makes 1 - naphthylamine - 4 - sulfonic acid sodium is widely applied in with all kinds of metal (such as Fe, zinc, Cd, Ni, etc.) complex, used for hazardous chemicals leakage monitoring equipment, optical device, gas absorption material in the synthesis and clinical medical research. Sodium 1-naphthalamine-4-sulfonate can also be used in thermal switch, optical switch and information storage element materials, DNA structure probe, DNA molecular optical switch and other fields.
