2706-28-7 - Introduction
4-amino-1,1 '-azobenzene-3,4'-disulfonic acid is an organic compound with the chemical formula C12H12N6O6S2. It is a white solid, soluble in water.
This compound is often used as a dye and indicator. Its finished product is a red to purple compound that can be used to dye textiles, paper and certain plastics. In addition, it can also be used as an acid-base indicator due to its color change under acid-base conditions.
4-amino-1,1 '-azobenzene-3,4'-disulfonic acid can be prepared by coupling reaction of p-nitroaniline. First, nitroaniline reacts with sodium nitrite under acidic conditions to form nitrosoaniline, which then reacts with disulfuric acid to form the target product.
When using and handling 4-amino-1,1 '-azobenzene-3,4'-disulfonic acid, you need to pay attention to the following safety information:
1. Avoid inhaling dust and avoid skin contact to prevent allergic reactions.
2. In carrying and storage, to avoid contact with strong acid, alkali and other substances.
3. Wear appropriate personal protective equipment such as gloves, goggles and protective clothing when using.
4. Pay attention to a well-ventilated environment during use to prevent the accumulation of harmful gases.
5. Seek medical help immediately if ingested or inhaled.
