For example, the semicarbazone of acetone would have the structure (CH3)2C=NNHC(=O)NH2. C(=N)(NN)O CopyCopied, DUIOPKIIICUYRZ-UHFFFAOYSA-N In organic chemistry, a semicarbazone is a derivative of imines formed by a condensation reaction between a ketone or aldehyde and semicarbazide. Experimental Melting Point: 231 °C Jean-Claude Bradley Open Melting Point Dataset 9358: 213.5 °C Biosynth J-501846: 231 °C MolMall 20474: 213.5-217.5 °C Sigma-Aldrich ALDRICH-568449: Experimental LogP: 0.744 LabNetwork LN00240254: Miscellaneous. A thiosemicarbazone is an analog of a semicarbazone which contains a sulfur atom in place of the oxygen atom. CopyCopied, CSID:5008, http://www.chemspider.com/Chemical-Structure.5008.html (accessed 06:09, Nov 29, 2020) Solubility: 100 g/l (15 c) Specific Gravity/Density:Not available. Many semicarbazones are crystalline solids, useful for the identification of the parent aldehydes/ketones by melting point analysis. Semicarbazide hydrochloride. 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. Semicarbazide is frequently reacted with aldehydes and ketones to produce semicarbazones via a condensation reaction. Experimental Melting Point: 96 °C Jean-Claude Bradley Open Melting Point Dataset 21559: Experimental Boiling Point: 186.3 °C Chemenu CM186660: Experimental LogP:-2.166 LabNetwork LN01075682: Miscellaneous. semicarbazide group. A monocarboxylic acid amide that is urea where one of the amino groups has been replaced with hydrazine. Semicarbazide (SEM) carbamic acid hydrazide. Advanced Search | Structure Search. This is an example of imine formation resulting from the reaction of a primary amine with a carbonyl group. Clinical (1) ... Semicarbazide hydrochloride. Hydrazinecarboximidicacid (9CI) DTXSID7043823. It can also be used to prepare corrosion inhibitors. Semicarbazide hydrochloride is a general reagent used to synthesize semicarbazones from aldehydes and ketones. ZINC8035043. 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. Boiling Point: Not available. 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. Lopac-S-2201. Molecular Formula:CH5N3O.HCl Molecular Weight:111.53 Semicarbazones and thiosemicarbazones can be prepared by treatment of a ketone or aldehyde with semicarbazide or thiosemicarbazide (Scheme 16).The reaction is general acid catalysed, and the yield of semicarbazone and the rate of reaction are dependent on the pH of the reaction medium < 32JA2881, 59JA475, 66BSB601 >.
