thiosemicarbazide Chemical Properties,Usage,Production

Chemical Properties
white crystalline solid
General Description
N-Aminothiourea is a white crystalline powder and is odorless. N-Aminothiourea is used as a reagent for ketones and certain metals, for photography and as a rodenticide. N-Aminothiourea is also effective for control of bacterial leaf blight of rice. Not a registered pesticide in the U.S. N-Aminothiourea is a chemical intermediate for herbicides and a reagent for detection of metals.
Reactivity Profile
Isocyanates and thioisocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence, [Wischmeyer(1969)].
Health Hazard
N-Aminothiourea is highly toxic by ingestion. May induce goiter and cause delayed toxic effects in blood and skin. May be mutagenic in human cells.
Fire Hazard
When heated to decomposition, very toxic fumes of sulfur oxides and nitrogen oxides are emitted.
