The Uses of Thiocarbohydrazide
Thiocarbohydrazide is used in electron microscopy to produce electron-opaque deposits for ultra structural analysis. It is used in the synthesis of oxazine grass ketones.
Definition
ChEBI: Thiocarbohydrazide is a thiocarbonyl compound.
General Description
Crystalline needles and plates. Used in electron microscopy to produce electron-opaque deposits for ultra structural analysis.
Reactivity Profile
Thiocarbohydrazide is a thioamide, which may behave as a weak base and therefore will react with acids forming salts with production of heat. Thiocarbohydrazide may react with acids and reducing agents to form toxic hydrogen sulfide gas. This may be vigorous depending on the nature of the reducing agent. Organic amides/imides react with azo and diazo compounds to generate toxic gases. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Health Hazard
High oral toxicity.
Fire Hazard
When heated to decomposition Thiocarbohydrazide emits very toxic fumes of nitrogen oxides and sulfur oxides.
