2-Aminothiazole Properties and Stability
Avoid light. Avoid contact with strong oxidants, strong acids, acid chlorides and acid anhydrides.
How to store 2-Aminothiazole
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep container tightly closed. It should be stored separately from oxidants, acids, and edible chemicals, and should not be mixed. Equipped with the appropriate variety and quantity of fire equipment. Storage areas should be provided with suitable materials to contain spills.
2-Aminothiazole synthetic method
It is obtained by cyclization of thiourea and chloroacetaldehyde (or ethanol and chlorine, or α, β dichloroethyl ether). The reactor was charged with hot water, thiourea and α,β-dichloroethyl ether. Reflux with stirring for 2h. After cooling, sodium hydroxide solution was added through a dropping funnel to make the solution alkaline, and 2-aminothiazole crystals were precipitated. Diethyl ether was then added to dissolve it. The ether layer was separated, washed with water, dried over anhydrous sodium sulfate, and the ether was evaporated to obtain the crude product. Recrystallization from ethanol gave yellow crystals. Yield 80%, melting point 90°C.

【 Standard】
GB/T 20435-2006
【 Application】
It’s a basic raw material of silicone oil (modified silicone oil),silicone emulsion,silicone rubber ,silicone
resin and other silicone products, and can also be directly used as rubber filler treatment agents
or raw material for cosmetics.
