Calle J Brookes Biography & Facts

Semicarbazide is the chemical compound with the formula OC(NH2)(N2H3). It is a water-soluble white solid. It is a derivative of urea. Synthesis The compound prepared by treating urea with hydrazine: OC(NH2)2 + N2H4 → OC(NH2)(N2H3) + NH3A further reaction can occur to give carbohydrazide: OC(NH2)(N2H3) + N2H4 → OC(N2H3)2 + NH3Derivatives Semicarbazide is frequently reacted with aldehydes and ketones to produce semicarbazones via a condensation reaction. This is an example of imine formation resulting from the reaction of a primary amine with a carbonyl group. The reaction is useful because semicarbazones, like oximes and 2,4-DNPs, typically have high melting points and crystallize, facilitating purification or identification of reaction products. Properties Semicarbazide products (semicarbazones and thiosemicarbazones) are known to have an activity of antiviral, antiinfective and antineoplastic through binding to copper or iron in cells. Uses, occurrence, detection Semicarbazide is used in preparing pharmaceuticals including nitrofuran antibacterials (furazolidone, nitrofurazone, nitrofurantoin) and related compounds. It is also a product of degradations of the blowing agent azodicarbonamide (ADC). Semicarbazide forms in heat-treated flour containing ADC as well as breads made from ADC-treated flour.Semicarbazide is used as a detection reagent in thin layer chromatography (TLC). Semicarbazide stains α-keto acids on the TLC plate, which can then be viewed under ultraviolet light. See also Biurea - another product of reaction of urea with hydrazine Carbazide - structurally related with the general formula (R2NNH)2C(O) Semicarbazide-cadmium therapy thiosemicarbazideReferences External links Compounds Containing a N-CO-N-N or More Complex Group.
