Description

Poly(Styrene-Co-Vinylbenzyl Chloride-Co-Divinylbenzene) is a functionalized cross-linked copolymer resin, widely recognized as a key intermediate and support material in advanced chemical synthesis. Its value lies in the reactive chloromethyl groups, which provide versatile sites for further chemical modification and immobilization of catalysts, ligands, or other functional moieties. This material is essential for researchers and manufacturers in the fields of polymer chemistry, solid-phase synthesis, and the development of specialized chromatographic media.

Application

• Polymer-Supported Reagent Synthesis: Serves as a robust, insoluble polymeric backbone for anchoring catalysts, scavengers, or reagents used in combinatorial chemistry and parallel synthesis.
• Solid-Phase Organic Synthesis (SPOS): Acts as a versatile solid support for the stepwise construction of peptides, oligonucleotides, and small molecule libraries.
• Functional Resin Production: Used as a precursor for manufacturing ion-exchange resins, chelating resins, and specialty adsorbents through further chemical modification.
• Chromatography Media: Forms the base matrix for the development of high-performance liquid chromatography (HPLC) and affinity chromatography stationary phases.
• Polymer Grafting & Modification: Provides reactive sites for grafting polymers or attaching specific functional groups to tailor surface properties for specialized applications.

Quality Control

Our production of Poly(Styrene-Co-Vinylbenzyl Chloride-Co-Divinylbenzene) follows stringent quality protocols to ensure batch-to-batch consistency and performance. Key parameters such as chlorine content (degree of functionalization), particle size distribution, cross-linking density, and swelling properties are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment to support your quality assurance and R&D 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). This material is stable under these conditions but should be kept away from strong bases and incompatible organic solvents as indicated by its chemical properties.
