Product Name:Sodium methylarsonate
English Name:Sodium methylarsonate
CAS No.:2163-80-6
Aliases:Monosodium methylarsonate, MSMA, Methylarsonic acid monosodium salt
Molecular Formula:CH4AsNaO3
Physical Properties:White crystalline powder, freely soluble in water, slightly soluble in ethanol, insoluble in ether, acetone and other organic solvents. No distinct melting point; decomposes at approximately 200 °C when heated. Relative density approximately 1.6.
Uses:Mainly used for post-emergence control of annual grasses and certain broadleaf weeds in crop fields such as cotton, sugarcane and citrus orchards. It is also applied for total vegetation control on non-crop land, lawns and railway ballast. In addition, it can be used as an intermediate for synthesizing other organoarsenic compounds.
