Guanidine Hydrobromide is the hydrobromide salt of guanidine, a strong organic base. It is widely used as a chaotropic agent and protein denaturant in biochemistry to disrupt non-covalent interactions, facilitating the study and purification of proteins and nucleic acids. In organic synthesis, it serves as a reagent or source for generating the free guanidine base, aiding reactions in pharmaceutical production, peptide synthesis, and the preparation of other organic compounds. It is also applied in the extraction and solubilization of biomolecules, as well as in some industrial processes for dyes and stabilizers.
