5,6-diamino-2-sulfanylidene-1H-pyrimidin-4-one - Introduction
4,5-diamino-2-thiouracil (DASUTM) is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: DASUTM is a white crystalline solid.
-Solubility: It has low solubility in water, but it can be dissolved in organic solvents such as ethanol and dimethylformamide.
Use:
-Chemical reagents: DASUTM is widely used in the preparation of chemical reagents, especially for the preparation of pyrimidine and thiourea compounds.
-Insecticide: DASUTM can also be used as one of the raw materials of pesticides for agriculture and horticulture.
Preparation Method:
The preparation of DASUTM can be carried out by the following steps:
1. First, a thiouracil intermediate is obtained by reacting ammonium thiocyanate and dimethylformamide at an appropriate temperature.
2. Then, through the amination reaction, the thiouracil intermediate is converted into the final product 4,5-diamino-2-thiouracil.
Safety Information:
- DASUTM is a chemical reagent with certain toxicity. Wear protective glasses and gloves during operation to avoid direct contact with skin and mucous membranes.
-Avoid inhaling its dust or gas to avoid discomfort. If there is an abnormality, remove the affected person from the air quickly and seek medical help.
-Store it in a dry, well-ventilated place to avoid contact with oxidants and strong acids.
-Follow the correct treatment methods, including appropriate waste treatment and recycling measures, to reduce the risk of environmental pollution.
