  1. Semicarbazone

    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. For ketones: For aldehydes: For example, the semicarbazone of acetone would have the structure (CH3)2C=NNHCNH2. A thiosemicarbazone is an analog of a semicarbazone which contains a sulfur atom in place of the oxygen atom. Some semicarbazones, such as nitrofurazone, and thiosemicarbazones are known to have anti-viral and anti-cancer activity, usually mediated through binding to copper or iron in cells. Many semicarbazones are crystalline solids, useful for the identification of the parent aldehydes/ketones by melting point analysis.
