CAS: 108-19-0
Molecular Formula: C2H5N3O2
Molecular Weight: 103.08　
Product description:Long white crystals. Melting point 190 ℃ (decomposition), relative density 1.467 (- 5/4 ℃). The water crystals containing four molecular crystal water, at about 110 ℃ water loss. Soluble in alcohol, very slightly soluble in ether.Will, urea, water, disodium hydrogen phosphate and mixed heat to dissolve. Up to 150-150 ℃, heat preservation 2 h. Reaction, poured the reactants into the water, the place for the night, filter out crystallization of crude products, by the dilute ammonia recrystallization, finished product biuret. In urea production to middle urine as a raw material, through high heat thermal shrinkage, separation, drying is the finished product.Used as pharmaceutical intermediates, growth hormone, foaming agent, and paint.
