Description

Methanamine, N,n-Dimethyl-, Reaction Products With (Chloromethyl)Ethenylbenzene-Divinylbenzene Polymer And Sodium Hydroxide is a quaternary ammonium functionalized ion exchange resin, a key material for selective adsorption and catalysis. This product is engineered to provide high capacity and stability for demanding separation and purification processes in industrial and laboratory settings. It is essential for manufacturers and research facilities in the pharmaceutical, chemical synthesis, and water treatment sectors requiring advanced functional polymers.

Application

• Catalyst Support in organic synthesis reactions, particularly for acid-catalyzed processes.
• Ion Exchange Medium for the purification and demineralization of process water and specialty chemicals.
• Selective Adsorbent for the recovery of precious metals or the removal of specific anions from industrial streams.
• Pharmaceutical Intermediate Purification, used in fixed-bed columns to isolate or purify active pharmaceutical ingredients (APIs).
• Chromatographic Separation as a stationary phase in preparative and process-scale chromatography.
• Chemical Scavenging to remove impurities or by-products from reaction mixtures in multi-step syntheses.

Quality Control

Every batch of our ion exchange resins is manufactured and tested under a strict quality management system. Key parameters such as ion exchange capacity, moisture content, particle size distribution, and functional group density are rigorously verified. Certificates of Analysis (COA) detailing all test results are provided to ensure full traceability and compliance with your technical requirements.

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). Due to its hygroscopic nature, the container must be kept sealed when not in use to prevent moisture absorption, which can affect performance. Keep away from strong oxidizing agents.
