Ammonium sulfamate
Ammonium sulfamate (CAS: 7773-06-0), with the molecular formula NH4SO3NH2 and a molar mass of 114.12 g/mol, is an inorganic salt. It is primarily recognised for its efficacy as a non-selective herbicide, effective against a broad spectrum of weeds, grasses, and brush. Its application extends to industrial vegetation control, notably in areas like railway lines and industrial sites. It is also used in some chemical synthesis processes.
Herbicide and Plant Growth Regulator
Ammonium sulfamate is a potent, non-selective herbicide used to control a wide range of weeds, brush, and woody plants. It is particularly effective in industrial areas, rights-of-way, and non-crop land.
Flame Retardant
This compound has been historically used as a flame retardant for fabrics, paper, and other cellulosic materials, although this application is less common today. It works by releasing ammonia and water when heated.
Chemical Synthesis
Ammonium sulfamate serves as a reagent in certain chemical synthesis pathways. Its reactive groups allow it to be incorporated into various organic and inorganic compounds.
