Chemische Eigenschaften
Thiosemicarbazide is an odorless, white crystalline powder.Verwenden
Used in TLC to stain alpha-keto acidsThiosemicarbazide is used as a reagent for ketones as well as chemical intermediate. It is involved in the detection of metals. It is also used in photography. Further, it is effective for controlling bacterial leaf blight in rice. In addition to this, it is used to prepare 1,3,4-thiadiazoles.Allgemeine Beschreibung
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.Reaktivit?t anzeigen
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.Brandgefahr
When heated to decomposition, very toxic fumes of sulfur oxides and nitrogen oxides are emitted.Sicherheitsprofil
Poison by ingestion, intraperitoneal, and intravenous routes. Questionable carcinogen with experimental tumorigenic data. Human mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and SOx.m?gliche Exposition
Thiosemicarbazide is a dithiocarbamide compound is used as an intermedialte for pharmaceuticals and herbicides; as a reagent for ketones and certain metals; in certain photography and dye operations; as a rodenticide. It is also effective for control of bacterial leaf blight of rice.Versand/Shipping

Crystallise thiosemicarbazide from H2O (solubility is 20.3% w/w at 80o). The hydrochloride has m 190-191o(dec, 184o also reported). It forms salts with heavy metals. [Beilstein 3 H 195, 3 I 79, 3 II 134, 3 III 315, 3 IV 374.]Inkompatibilit?ten
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.) and strong reducing agents; contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May react with nitrates.Thiosemicarbacid Upstream-Materialien And Downstream Produkte
