Uses As a reagent for detection of metals.

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.
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.
Thiosemicarbazide CAS 79-19-6 Pharmaceutical Grade Raw Materials For Analytical Reagents 0

Intermediate for medicine and pesticide.It's also a rat agent.Used for determination of chromium, the identification of aldehydes, ketones and sugar, and preparation of 1, 2, 4-triazole.The reagent and the carboxylic acid condensation were obtained from 1- formacyl - 3-amino-thiourea, and 3- sulfhydryl - 1, 2, 4-triazole with alkali cyclization, and 1, 2, 4-triazole were removed with nitric acid oxidation.

This product is a white crystalline powder. Soluble in water and ethanol, easy to react with aldehydes and ketones generate specific crystal product, also easy to react with carboxylic acid

mainly used for medicine, pesticide intermediates synthesis of raw materials. Pharmaceutical used for synthesis of sulphonamide antihypertensive agents, diuretics, etc., used in the synthesis of herbicide, pesticide rodenticide and acaricide, bactericide and growth inhibitors, etc. Can also be used for photographic light-sensitive materials, wood light discoloration preventing agent, removal of heavy metals in chelate polymer synthetic material, etc. Also used for the determination of chromium, aldehyde ketone appraisal analysis reagent, rubber additives, synthetic resins and other additives.
