I. [Product Description]
MA-PEG-Tosyl (Methacrylate-Polyethylene Glycol-Tosyl) is a versatile organic intermediate that combines the polymerizability of methacrylate and the high reactivity of tosyl. It is widely used in the synthesis of polymer materials and the field of bioconjugation. Its PEG segment provides excellent water solubility and biocompatibility, and it can participate in complex chemical reactions as a catalyst carrier or pharmaceutical intermediate.

II. [Product Details]

III. [Application Fields]
1. As a functional intermediate for the synthesis of polymer materials, it is used to prepare amphiphilic block copolymers.
2. The activated tosyl sites are used for the site-specific conjugation of biomolecules (such as proteins and nucleic acids).
3. Surface functionalization of PEG-modified nanoparticles to improve dispersion and stability.
4. As a cross-linking agent in photoinitiated polymerization systems to regulate the mechanical properties of materials.
5. As a templating agent in the preparation of porous materials to optimize pore size distribution and porosity.
