Product Name:Semicarbazide
English Name:Semicarbazide
CAS No.:57-56-7
Aliases:Aminourea, Carbamylhydrazine
Molecular Formula:CH5N3O
Physical Properties:White crystalline powder, freely soluble in water and ethanol, insoluble in ether, slightly soluble in benzene. Melting point approximately 96°C, density approximately 1.286 g/cm³, boiling point approximately 190°C (decomposes). Stable in air, but may decompose upon heating or in contact with strong oxidizers.
Uses:Used as an intermediate in pharmaceuticals, agrochemicals and organic synthesis, and as an important raw material for nitrofuran drugs. Also commonly used for qualitative identification and separation of aldehydes and ketones, as well as a derivatization reagent in chemical analysis.
Technical Specifications:
Assay (on dry basis) ≥98%
Melting point range 95–98°C
Loss on drying ≤0.5%
Solubility in water: passes (1 g dissolves in 10 mL water)
