Properties and stability

This product is relatively unstable and can be hydrolyzed in aqueous solution to form ammonia and urea, so its toxicity is the same as that of urea. Its derivatives are generally more toxic than ureas.

Storage method

None

Synthesis method

Using dicyandiamide and ammonium salt (ammonium chloride) as raw materials, conduct a melting reaction at 170-230°C to obtain crude guanidine hydrochloride, which can be refined to obtain the finished product.

Purpose

1. Can be used as intermediates for medicines, pesticides, dyes and other organic synthesis. It can be used to synthesize 2-aminopyrimidine, 2-amino-6-methylpyrimidine, 2-amino-4,6-dimethylpyrimidine, and is used to manufacture sulfa drugs such as sulfadiazine, sulfamethylpyrimidine, and sulfadimethylpyrimidine. intermediate.

2. Guanidine hydrochloride (or guanidine nitrate) reacts with ethyl cyanoacetate to form 2,4-diamino-6-hydroxypyrimidine, which is used to synthesize the anti-anemia drug folic acid. It can also be used as an antistatic agent for synthetic fibers.

3. It can also be used as a protein denaturant.
