Description

Guanidinium Sulphate CAS NO 1184-68-5 is a high-purity inorganic salt widely used as a key intermediate and reagent in advanced chemical synthesis. Its primary value lies in its ability to act as a potent protein denaturant and chaotropic agent, making it indispensable for processes requiring the disruption of molecular structures. This product is essential for manufacturers and research institutions in the biotechnology, pharmaceutical, and specialty chemical sectors.

Application

• Protein Denaturation & Purification: A critical reagent in the extraction and purification of nucleic acids (DNA/RNA) and proteins, where it disrupts hydrogen bonding and solubilizes biomolecules.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of various active pharmaceutical ingredients (APIs), antiviral drugs, and guanidine-based compounds.
• Biotechnology Research: Used in laboratory protocols for cell lysis, enzyme inactivation, and as a component in buffer solutions for chromatography and electrophoresis.
• Chemical Synthesis: Acts as a precursor for manufacturing guanidine derivatives, sulfonamides, and other nitrogen-containing specialty chemicals.
• Industrial Processes: Employed in specific textile treatments, resin manufacturing, and as a catalyst or stabilizer in select polymerization reactions.
