Description

Cyanomethyl Dithiobenzoate is a specialized organosulfur compound that serves as a versatile intermediate and chain transfer agent in advanced polymer synthesis. Its value lies in its ability to precisely control polymer architecture and molecular weight, which is critical for developing materials with tailored properties. This product is essential for researchers and manufacturers in the polymer, specialty chemical, and pharmaceutical industries who require high-purity intermediates for controlled radical polymerization processes.

Application

• As a chain transfer agent (CTA) or reversible addition-fragmentation chain-transfer (RAFT) agent in controlled/living radical polymerization.
• Key intermediate for the synthesis of functional polymers with specific end-group functionality.
• Used in research and development of block copolymers, star polymers, and other complex polymer architectures.
• Production of surface-active agents and polymers for coatings and adhesives.
• Intermediate in the synthesis of pharmaceutical compounds and other fine chemicals.
• Material science research for developing novel polymeric materials with enhanced mechanical or thermal properties.

Quality Control

Our Cyanomethyl Dithiobenzoate is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, which is critical for its performance as a polymerization agent. Each lot undergoes comprehensive analytical testing, including chromatographic purity assays and structural confirmation. A Certificate of Analysis (COA) detailing specific results for purity, identity, and related substances is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials.
