Description and Uses

Ammonium sulfamate (or ammonium sulphamate) is a white crystalline solid, readily soluble in water. It is a salt formed from ammonia and sulfamic acid. Based on its good performance, it is widely used in industrial production and scientific research. Ammonium sulfamate is used as a herbicide, a composting accelerator in horticultural settings, a flame retardant, and so on.

Ammonium sulfamate (AMS) is an inorganic herbicide used for control of woody plants and herbaceous perennials.
