Thiocarbohydrazide is a common reagent in Transmission and Scanning Electron Microscopy. Chemical Formula: CH 6 N 4 S. Layman's explanation: Thiocarbohydrazide (TCH) was discovered in 1908 by R. Stolle. Wilson and Gula were the first to begin studies on this new molecule. Audrieth reinvestigated and improved the original synthesis of TCH and Sandstrom and Beyer were among the first to use TCH.

RESULTS: Through this study, the main factors that affect the yield of thiocarbohydrazide were found, together with the optimal factor levels. It was shown that the reflux temperature was the most significant factor affecting the yield of thiocarbohydrazide, followed by the molar ratio of hydrazine to carbon disulfide. The optimum factor levels were a reflux time of 6 h, molar ratio of.
