Moiety3
In this work, semicarbazones containing a tert-butyl carbazate moiety was examined for the rhodium(III)-catalyzed cycloaddition reaction with alkynes. (edu.hk)
The semicarbazone moieties of these independent mol-ecules (I and II) are essentially planar [maximum deviation of 0.042 (1) Å in mol-ecule I and 0.041 (1) Å in mol-ecule II], with the terminal phenyl rings twisted away from the mean plane of the semicarbazone moiety, making dihedral angles of 60.26 (8) and 28.76 (9)° in mol-ecule I and 31.07 (9) and 35.45 (8)° in mol-ecule II.

NNHC1
For ketones H2NNHC(=O)NH2 + RC(=O)R → R2C=NNHC(=O)NH2 For aldehydes H2NNHC(=O)NH2 + RCHO → RCH=NNHC(=O)NH2 For example, the semicarbazone of acetone would have the structure (CH3)2C=NNHC(=O)NH2. (wikipedia.org)
Maximal electroshock2
After intraperitoneal injection to mice, the semicarbazones were examined in the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ), and neurotoxicity (NT) screens. (nih.gov)
Methods: A series of twenty-six compounds of N 4 -(4-bromo-3-methylphenyl) semicarbazones were synthesized and evaluated for the anticonvulsant activity in the maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole (scPTZ) seizure threshold tests. (zju.edu.cn)
Ketones2
Many semicarbazones are crystalline solids, useful for the identification of the parent aldehydes/ketones by melting point analysis. (wikipedia.org)
Ketones and aldehydes, for example, will react to form semicarbazones that can be recrystallized and then identified by melting point. (stackexchange.com)
