Semicarbazide
Appearance
In organic chemistry, a Semicarbazide is a derivative of urea, where NH2 on one side has been replaced with H2NNH2 hydrazine, yielding H2NNHC(=O)NH2.
Semicarbazide is used as a detection reagent on thin layer chromatography. Semicarbazide stains for α-Keto acids on the TLC plate, which must then be viewed under a UV light to see the results.
