Storage method

This product should be sealed and stored in a cool, dry place away from light.

Synthesis method

1.It is produced by heating reaction using thiourea and hydrazine hydrate as raw materials.


2.Hydrazine sulfate is prepared from hydrazine hydrate and sulfuric acid, reacts with ammonium thiocyanate to form hydrazine thiocyanate, and then reacts with acetaldehyde and hydrolyzes to obtain thiosemicarbazide.

Purpose

This product is an organic synthesis intermediate, used for the synthesis of anti-tuberculosis drugs thiosemicarbazide and sulfa drugs, and Rodenticide can also be used as an analytical reagent for the quantification of chromium and the identification of aldehydes and ketones. In addition, this product is also used as a pesticide intermediate, rubber additive and synthetic resin additive.
