Sulfamic acid 5329-14-6
Aminosulfonic acid is a colorless, odorless, non-toxic solid strong acid. Its aqueous solution has the same strong acid properties as hydrochloric acid and sulfuric acid, but its corrosiveness to metals is much lower than that of hydrochloric acid. It has very low toxicity to the human body, but it cannot be in contact with the skin for a long time, let alone enter the eyes.

1. Aminosulfonic acid aqueous solution has a slow effect on the corrosion products of iron. Some sodium chloride can be added to slowly produce hydrochloric acid, thereby effectively dissolving iron scale.
2. It is suitable for removing scale and corrosion products on the surface of equipment made of iron, steel, copper, stainless steel and other materials.
3. Aminosulfonic acid aqueous solution is the only acid that can be used for cleaning galvanized metal surfaces. The cleaning temperature is generally controlled at no more than 66°C (to prevent the decomposition of aminosulfonic acid) and the concentration does not exceed 10%.
4.Aminosulfonic acid can be used as a reference reagent for acid-base titration in analytical chemistry.
5.It is used as a herbicide, fire retardant, softener for paper and textiles, shrink-proof, bleaching, softener for fibers, and cleaner for metals and ceramics.
6.It is also used for diazotization of dyes and pickling of electroplated metals.
