Description

Polystyrene, Crosslinked, Tertiary Amine is a functionalized polymeric resin featuring a stable, insoluble polystyrene backbone with reactive tertiary amine groups. This material is engineered to serve as a robust and versatile anion exchange resin and catalyst support, offering high chemical stability and reusability. It is essential for industries requiring advanced separation, purification, and catalytic processes, including pharmaceutical synthesis, water treatment, and fine chemical manufacturing.

Application

• Anion Exchange Chromatography: For the purification and separation of proteins, nucleotides, and organic acids in biopharmaceutical and life science research.
• Catalyst Support: As a solid support for immobilizing catalysts in organic synthesis, facilitating reactions like alkylation, acylation, and phase-transfer catalysis.
• Water Treatment: Removal of anions such as nitrate, perchlorate, and chromate from industrial wastewater and drinking water.
• Pharmaceutical Intermediates: Use in the synthesis and purification of active pharmaceutical ingredients (APIs) and intermediates.
• Sugar Decolorization & Demineralization: Purification processes in the food and sweetener industry.
• Metal Recovery: Selective extraction and recovery of precious or heavy metals from process streams in hydrometallurgy.
• Laboratory Scale Separations: As a versatile medium for method development and small-scale purification in R&D laboratories.

Quality Control

Our Polystyrene, Crosslinked, Tertiary Amine is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including ion exchange capacity, moisture content, particle size distribution, and functional group integrity. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to ensure traceability and batch-to-batch consistency for your critical processes.

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 moisture-sensitive; ensure the container is sealed after use to prevent moisture uptake, which can affect performance.
