설명

일반 설명

Ammonium sulfate is a versatile inorganic salt commonly used as an agriculture fertilizer as a nitrogen and sulfur source. It is also used as an extracting agent to extract metals such as iron, chromium, aluminum, and calcium. Furthermore, ammonium sulfate is employed in the purification of antibodies either from serum or ascitic fluids and in precipitating or fractionating proteins.

애플리케이션

Ammonium sulfatecan be used as a reagent in the palladium-catalyzed amination of aryl halidesto arylamines in the presence of sodium tert-butoxide. It can also beused as a catalyst in the hexamethyldisilazane-mediated reaction ofquinazolin-4(3H)-ones with primary amines to synthesize 4-aminoquinazolines.
