Properties and stability

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

Purpose:1. It can be used as intermediate of medicine, pesticide, dye and other organic synthesis. It can be used to synthesize 2-Aminopyrimidine, 2-amino-6-methylpyrimidine and 2-amino-4,6-dimethylpyrimidine. It is an intermediate for the manufacture of sulfadiazine, sulfamethylpyrimidine and sulfadimidine.

 

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

 

3. It can also be used as protein denaturant.

 

  1. As a strong denaturant in the experiment of extracting total RNA. Guanidine hydrochloride solution can dissolve protein, cause cell structure damage, nuclear protein secondary structure damage, dissociate from nucleic acid, in addition, RNase can be inactivated by reducing agent such as guanidine hydrochloride.

synthetic method

Using dicyandiamide and ammonium salt (ammonium chloride) as raw materials, the crude guanidine hydrochloride was obtained by melting reaction at 170-230 ℃, and the finished product was obtained by refining.
