Description
Analysis Note
Solubility:
0.5 g are completely soluble and give a clear solution in 10 mL water or also in 10 mL ethanol.
Sensitivity test:
0.05 mg urea in 3 mL water and 5 mL conc. HCl together with a 3% solution in water of diacetylmonoxime heated on a water bath for 10 minutes give a light yellow color.
