Description

Benzene,Diethenyl-,Polymer With Ethenylbenzene And Ethenylethylbenzene,Chloromethylated,Trimethylamine-Quaternized,Carbonate is a specialized quaternary ammonium functionalized polymer, a high-performance anion exchange resin derived from a styrenic copolymer backbone. This compound is engineered for superior ion exchange capacity and chemical stability in demanding separation and purification processes. It is a critical material for industries requiring advanced water treatment, high-purity chemical production, and specialized catalytic applications.

Application

• Ion Exchange Chromatography: Used as a strong base anion exchange resin for the purification and separation of biomolecules, pharmaceuticals, and fine chemicals.
• Ultrapure Water Production: A key component in mixed-bed and polishing demineralizers for power generation, microelectronics, and laboratory water systems.
• Catalysis: Serves as a solid-supported phase transfer catalyst or reagent in organic synthesis reactions.
• Wastewater Treatment: Employed for the selective removal of anions, such as nitrates, chromates, and perchlorates, from industrial effluents.
• Sugar & Sweetener Decolorization: Used in the refining process to remove color bodies and ionic impurities.
• Pharmaceutical Intermediates: Facilitates the purification of active pharmaceutical ingredients (APIs) and intermediates.

Quality Control

Our anion exchange resins are manufactured under a strict quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent performance metrics such as ion exchange capacity, moisture holding capacity, particle size distribution, and chemical stability. Certificates of Analysis (COA) detailing these parameters are available upon request to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture uptake which can affect performance.
