Description

4-Cyano-4-[(ethylsulfanylthiocarbonyl)sulfanyl]pentanoic acid is a high-purity RAFT (Reversible Addition-Fragmentation Chain Transfer) agent, a critical component for controlled radical polymerization. This compound enables the precise synthesis of polymers with predetermined molecular weights, low polydispersity, and complex architectures. It is essential for researchers and manufacturers in advanced polymer science, materials development, and specialty chemical synthesis requiring tailored macromolecular structures.

Application

• RAFT Polymerization Agent: A key chain transfer agent for the controlled radical polymerization of acrylates, methacrylates, styrenics, and other vinyl monomers.
• Functional Polymer Synthesis: Enables the production of block copolymers, star polymers, and gradient copolymers with specific end-group functionality.
• Advanced Materials Research: Used in R&D for creating novel polymers with precise properties for coatings, adhesives, and drug delivery systems.
• Surface Modification: Facilitates the grafting of polymer brushes from surfaces for biomedical devices, sensors, and anti-fouling coatings.
• Bioconjugation: Serves as a building block for synthesizing polymers designed for conjugation with peptides, proteins, or other biomolecules.
• Specialty Resin Production: Applied in the development of high-performance resins for 3D printing, photolithography, and composite materials.
