Description

m-Peg6-2-Methylacrylate CAS NO 90784-86-4 is a specialized, hydrophilic polyethylene glycol (PEG) acrylate derivative, engineered to introduce controlled hydrophilicity and reactive functionality into polymer systems. This compound is a critical building block for synthesizing advanced materials with tailored properties for demanding applications. It is primarily utilized by R&D chemists and process engineers in the pharmaceutical, biomedical, and specialty polymer industries seeking to modify surface characteristics, enhance biocompatibility, and create functional hydrogels or drug delivery systems.

Application

• Pharmaceutical Linker & Conjugation: Used as a hydrophilic spacer arm in the synthesis of antibody-drug conjugates (ADCs) and protein-polymer conjugates to improve solubility and pharmacokinetics.
• Biomedical Hydrogels: A key monomer for creating cross-linked, water-swollen hydrogels for wound dressings, contact lenses, and tissue engineering scaffolds.
• Surface Modification & Functionalization: Imparts permanent hydrophilic coatings to surfaces (e.g., medical devices, membranes, and sensors) to reduce protein adsorption and fouling.
• Controlled Release Systems: Incorporated into polymer backbones for designing nanoparticles and micelles for the controlled release of active pharmaceutical ingredients (APIs).
• UV/Radiation Curable Resins: Serves as a reactive diluent and modifier in formulations for coatings, inks, and adhesives, enhancing flexibility and reducing viscosity.
• Research & Development: A versatile reagent for academic and industrial research in polymer chemistry, material science, and bioconjugation techniques.
