Description

2-Propenenitrile, Polymer With Diethenylbenzene And Ethenylbenzene, Chloromethylated, Trimethylamine-Quaternized, Hydroxide is a quaternary ammonium functionalized anion exchange resin, a key material in advanced separation and purification processes. Its value lies in its high ion exchange capacity and chemical stability, enabling efficient and selective removal of target anions from complex solutions. This product is essential for industries requiring high-purity water, catalysis, and specialized chemical synthesis.

Application

• Ultrapure Water Production: Critical for the electronics and power generation industries to remove ionic contaminants from feed water.
• Pharmaceutical Purification: Used in the isolation and purification of active pharmaceutical ingredients (APIs) and in drug delivery system development.
• Catalysis & Organic Synthesis: Serves as a solid-supported phase transfer catalyst or reagent in various organic transformations.
• Analytical Chemistry: Employed in ion chromatography columns for the separation and analysis of anions.
• Metal Recovery & Hydrometallurgy: Facilitates the selective extraction and concentration of precious or strategic metals from process streams.
• Sugar & Sweetener Decolorization: Used in the food industry to refine and decolorize sugar syrups and other sweeteners.
• Wastewater Treatment: Effective for the removal of nitrate, perchlorate, and other problematic oxyanions from industrial effluent.

Quality Control

Every batch of our anion exchange resin is produced under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as ion exchange capacity, moisture content, particle size distribution, and ionic form. Our quality protocols are designed to ensure consistent performance and batch-to-batch reproducibility, meeting the rigorous demands of pharmaceutical and high-tech industrial applications.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and a strong base. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide, which can reduce performance. Isolate from strong acids and oxidizing agents.
