Description

Perm Cross-Linked Resin CAS NO 109489-65-8 is a specialized, high-performance polymeric material engineered for demanding separation and purification processes. Its value lies in its exceptional chemical stability, high surface area, and tailored pore structure, which enable superior selectivity and binding capacity. This resin is critically needed by manufacturers and research facilities in the pharmaceutical, biotechnology, fine chemical, and water treatment industries for applications requiring robust and reliable media.

Application

• Chromatographic Separation: Used as a stationary phase in high-performance liquid chromatography (HPLC) and preparative chromatography for the purification of pharmaceuticals, natural products, and peptides.
• Ion Exchange Processes: Effective for demineralization, deionization, and selective removal of ions in ultrapure water production and hydrometallurgy.
• Catalyst Support: Serves as a stable, inert support matrix for heterogeneous catalysts in organic synthesis and chemical manufacturing.
• Adsorption & Filtration: Employed in fixed-bed adsorbers for the removal of organic contaminants, color bodies, and endotoxins from process streams and final products.
• Solid-Phase Synthesis: Acts as a scaffold for the synthesis of oligonucleotides, peptides, and other complex molecules where a stable, functionalized support is required.
• Analytical Sample Preparation: Utilized in solid-phase extraction (SPE) cartridges for the clean-up and concentration of analytes prior to instrumental analysis.
