Ammonium Sulfate 99% AR Grade Reagent
Cas Number:7783-20-2
Formula: (NH4)2SO4
Molar Mass:132.14
EC Number:231-984-1
Physicochemical properties:
Colorless crystal or white particles. Odorless. It will decompose above 280 °C. Solubility in water (g/100g saturated solution): 41.22 at 0 °C, 43.47 at 25 °C, 50.42 at 100 °C. It is insoluble in ethanol and acetone. The pH of the 0.1 mol/L aqueous solution is 5.5. The relative density is 1.77. The refractive index is 1.521. Low toxicity, half lethal dose (rat, oral) 3000mg/kg. Irritating.
Usage:
Biological preparations. Bacterial culture. Precipitating proteins. Spectrum analysis. A sand culture medium is prepared in a single sports species. Urine test.
Packing:
