Description

4-Vinylbenzenesulfinic Acid Sodium Salt is a versatile organosulfur compound that serves as a key reactive intermediate in advanced polymer synthesis. Its value lies in its dual functionality, featuring both a polymerizable vinyl group and a sulfinate moiety, enabling its use as a monomer, chain transfer agent, or initiator component. This chemical is essential for researchers and manufacturers in the polymer, specialty chemical, and pharmaceutical industries seeking to develop novel materials with specific properties.

Application

• Polymer Chemistry: As a functional monomer for the synthesis of polyelectrolytes, ion-exchange resins, and stimuli-responsive polymers.
• Controlled Radical Polymerization: Acting as a reversible chain transfer agent or sulfinyl-based initiator in techniques like RAFT polymerization.
• Surface Modification: For grafting polymer brushes onto substrates to alter surface energy, adhesion, or biocompatibility.
• Pharmaceutical Intermediates: Utilized in the synthesis of sulfone or sulfonamide-containing drug candidates and bioactive molecules.
• Crosslinking Agent: In the formulation of hydrogels, coatings, and adhesives where ionic or covalent crosslinking is desired.
• Material Science Research: For developing novel functional materials, including conductive polymers and self-assembling systems.

Quality Control

Our 4-Vinylbenzenesulfinic Acid Sodium Salt is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR, NMR), and impurity profiling, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing all specifications and results is provided with every shipment to guarantee traceability and compliance with your research or production 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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light to maintain stability and purity.
