thumb|right|General chemical structure of a semicarbazone thumb|right|Nitrofurazone is a semicarbazone used as an antiseptic In organic chemistry, a semicarbazone is a derivative of imines formed by a condensation reaction between a ketone or aldehyde and semicarbazide. They are classified as imine derivatives because they are formed from the reaction of an aldehyde or ketone with the terminal -NH2 group of semicarbazide, which behaves very similarly to primary amines.

==Formation== For ketones H2NNHC(=O)NH2 + RC(=O)R → R2C=NNHC(=O)NH2 For aldehydes H2NNHC(=O)NH2 + RCHO → RCH=NNHC(=O)NH2
