Description

Pyridine, 4-Ethenyl-, Polymer With Diethenylbenzene And Ethenylethylbenzene is a specialized cross-linked polymeric resin derived from functionalized pyridine monomers. This material matters for its unique combination of chemical stability, porosity, and the presence of basic nitrogen sites, making it a valuable functional material for advanced separation and catalysis. Industries requiring high-performance adsorbents, ion-exchange media, or catalyst supports, particularly in fine chemical synthesis, water treatment, and pharmaceutical purification, are the primary users of this polymer.

Application

• Ion-Exchange Resin: For the selective removal of heavy metal ions or specific anions from industrial wastewater and process streams.
• Catalyst Support: As a solid support for immobilizing transition metal catalysts used in hydrogenation, oxidation, and cross-coupling reactions.
• Chromatographic Separation Media: In preparative and process-scale chromatography for the purification of pharmaceuticals, natural products, and fine chemicals.
• Scavenger Resin: To remove impurities, excess reagents, or catalysts from reaction mixtures in combinatorial chemistry and parallel synthesis.
• Solid-Phase Synthesis: As a functionalized polymer support for the synthesis of peptides, oligonucleotides, or small molecule libraries.
• Gas Adsorption: For the capture of acidic gases (e.g., CO2, SO2) or volatile organic compounds in environmental control applications.

Quality Control

Our polymeric resins are manufactured under strict quality management systems. Each batch undergoes rigorous testing for critical parameters including particle size distribution, porosity, swelling capacity, ion-exchange capacity, and functional group loading to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The resin is hygroscopic (moisture-sensitive); ensure the container is sealed after use to prevent moisture uptake which may affect performance.
