Description

Amberlite CG-50 is a weakly acidic, macroreticular cation exchange resin based on a methacrylic acid-divinylbenzene copolymer. This product is essential for the selective adsorption, purification, and separation of basic compounds, particularly in applications requiring high capacity and chemical stability. It is widely utilized by professionals in the pharmaceutical, biotechnology, and fine chemical industries for downstream processing, including the isolation of antibiotics, peptides, and alkaloids.

Application

• Pharmaceutical Purification: Isolation and purification of basic antibiotics (e.g., streptomycin, neomycin) and other cationic drug substances.
• Biomolecule Separation: Chromatographic separation of proteins, peptides, and enzymes in biochemical research and production.
• Alkaloid Extraction: Recovery and purification of natural alkaloids and other nitrogen-containing compounds from plant extracts.
• Catalysis: Use as a solid acid catalyst support in various organic synthesis reactions.
• Water Treatment: Softening and demineralization of water in specific industrial processes.
• Analytical Chemistry: Serving as a stationary phase for ion-exchange chromatography in analytical laboratories.
