Description and Uses
Guanidine hydrochloride is used for purification of proteins and nucleic acids. It can be used as a medicine, organic synthesis intermediate and is used in dyes. It acts as an intermediate in the preparation of sulfadiazine, which is an important raw material for sulfamethyldiazine, sulfamethazine and folic acid. It is utilized in the synthesis of 2-amino-pyrimidine, 2- amino -6- methyl-pyrimidine and 2-amino -4,6 - dimethyl-pyrimidine. Also used in RNA isolation to dissociate nucleoproteins and inhibit RNase.
