Description

2-Propenoic acid, methyl ester, polymer with diethenylbenzene and ethenylethylbenzene, reaction products with N,N-dimethyl-1,3-propanediamine, chloromethane-quaternized, chloride is a high-performance, quaternary ammonium-functionalized polymeric resin designed for specialized separation and purification processes. This material matters for its strong cationic exchange capacity and tailored surface chemistry, enabling selective binding in complex matrices. It is primarily needed by manufacturers in the pharmaceutical, biotechnology, and fine chemical industries for applications requiring high-purity isolation, such as chromatography and catalyst recovery.

Application

• Ion-Exchange Chromatography: Used as a stationary phase for the purification of proteins, peptides, and other biomolecules.
• Catalyst Recovery & Recycling: Effective in scavenging and recovering precious metal catalysts or ionic species from reaction mixtures.
• Water Treatment: Employed in specialized industrial water purification systems to remove anionic contaminants and organic matter.
• Pharmaceutical Intermediate Purification: Critical for polishing steps in the synthesis of active pharmaceutical ingredients (APIs) to meet stringent purity standards.
• Analytical Sample Preparation: Used in solid-phase extraction (SPE) cartridges for the clean-up and concentration of analytes prior to HPLC or GC analysis.
• Dye & Pigment Processing: Aids in the removal of ionic impurities and color bodies during the manufacturing process.

Quality Control

Every batch of our quaternary ammonium-functionalized polymeric resin is manufactured under a strict quality management system. We perform rigorous in-process and final testing to ensure consistent performance characteristics such as ion-exchange capacity, particle size distribution, and moisture content. Certificates of Analysis (COA) documenting key specifications are provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at 15-25°C. Ensure the original container is kept sealed when not in use to prevent moisture uptake and maintain performance. Store away from strong oxidizing agents.
