colorless transparent or white crystals. Soluble in water, insoluble in ethanol and ether. Melting Point 175~177 °c (decomposition).
using hydrazine hydrate and urea as raw materials, the semicarbazide liquid is obtained by condensation, and then hydrochloric acid is added for acidification and complexation, and the product is obtained by water-cooling crystallization. Ammonia formed during the reaction can be used as a fertilizer after neutralization with a waste acid (hydrochloric acid, sulfuric acid mixture).
This product is the raw material of the pharmaceutical industry, for the preparation of nitrofuran and other drugs. It is also used as a reagent for the determination of ketones, aldehydes, chromatographic analysis reagents and solvents for the separation of hormones and essential oils.
