Description

4-Vinylbenzyl Chloride CAS NO 1592-20-7 is a versatile and highly reactive organic intermediate, primarily valued for its vinyl and benzyl chloride functional groups. This bifunctional nature makes it a critical building block for synthesizing advanced polymers, functional materials, and specialty chemicals. It is essential for R&D and production in the pharmaceutical, agrochemical, and advanced polymer industries seeking to create cross-linked networks or introduce reactive sites into larger molecules.

Application

• Polymer Chemistry: Key monomer for the synthesis of functionalized polystyrene resins, ion-exchange resins, and reactive polymers for solid-phase synthesis.
• Pharmaceutical Intermediates: Used in the production of active pharmaceutical ingredients (APIs) and for creating drug delivery systems through polymer conjugation.
• Agrochemical Synthesis: Serves as a precursor for manufacturing certain herbicides, fungicides, and plant growth regulators.
• Cross-linking Agent: Employed to create cross-linked polymeric networks for coatings, adhesives, and composite materials, enhancing thermal and mechanical properties.
• Surface Modification: Used to introduce reactive vinyl or chloromethyl groups onto surfaces (e.g., silica, polymers) for further functionalization in sensor or chromatography applications.
• Liquid Crystal & OLED Materials: Acts as a building block in the synthesis of monomers for advanced electronic and display materials.

Quality Control

Our 4-Vinylbenzyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, bases, and oxidizing agents. Recommended storage temperature is 2-8°C to maximize stability and shelf life. Keep container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and polymerization.
