Description

2-Ethanediyl)],.Alpha.-[2-Hydroxy-3-[(1-Oxo-2-Propenyl)Oxy]Propyl]-.Omega.-[2-Hydroxy-3-[(1-Oxo-2-Prpoly[Oxy (Methyl-1 CAS NO 66804-84-0 is a specialized reactive polymer, specifically a poly(ethylene glycol) derivative functionalized with methacrylate groups. This compound is a critical building block in advanced material science, valued for its ability to introduce cross-linkable sites and hydrophilic character into polymer networks. It is essential for manufacturers in the biomedical, pharmaceutical, and specialty coatings industries seeking to create hydrogels, drug delivery systems, and biocompatible surface modifications.

Application

• Biomedical Hydrogels: As a key macromer for creating photocrosslinkable, biocompatible hydrogels used in tissue engineering scaffolds and wound dressings.
• Drug Delivery Systems: Functional component for synthesizing PEGylated carriers and stimuli-responsive nanoparticles for controlled drug release.
• Surface Modification: Used to graft hydrophilic, non-fouling polymer brushes onto medical devices and implants to improve biocompatibility.
• Dental Materials: A reactive diluent and crosslinker in the formulation of dental composites and restorative resins.
• Contact Lens Materials: Imparts hydrophilicity and oxygen permeability in the production of soft contact lenses.
• Chromatography Media: Serves as a spacer arm or functional layer in the preparation of affinity chromatography columns for protein purification.
• Adhesives & Sealants: A modifier in UV-curable adhesive formulations, enhancing flexibility and adhesion to moist surfaces.

Quality Control

Our production of PEG Methacrylate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance. Each lot is characterized for critical parameters including degree of functionalization, molecular weight distribution, and residual monomer content. Certificates of Analysis (COA) documenting purity, assay, and specific tests are provided with every shipment. We support compliance with GMP and ISO 9001 standards for customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. This product is hygroscopic (moisture-sensitive) and light-sensitive (store away from light). For long-term stability, consider storage under an inert atmosphere such as nitrogen or argon. Keep away from heat and incompatible materials like strong oxidizers.
