guanidine hydrochloride usage and synthesis
application guanidine hydrochloride is used in rna isolation to dissociate nucleoproteins and inhibit rnase.
strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. this strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. this can be used as the first step in refolding proteins or enzymes into their active form. urea and dithiothreitol (dtt) may also be necessary.
drug intermediates guanidine hydrochloride drug used primarily as an intermediate in the manufacture of sulfadiazine, an important raw material sulfamethyldiazine, sulfamethazine and folic acid.
guanidine hydrochloride (or guanidine nitrate) and ethyl cyanoacetate reaction, cyclization of 2,4-diamino-6-hydroxy pyrimidine, folic acid for the synthesis of antianemic. furthermore guanidine hydrochloride also used synthetic anti-static agent.
preparation in dicyanodiamide and ammonium (ammonium chloride) as raw material, melt reaction at 170-230 ℃, guanidine hydrochloride obtained crude, refined products.
chemical properties white cryst. powder
usage cholinergic
usage guanidine has a good bacterial and fungicidal efficacy when used in low concentration and can also be used as disinfectant.
