Description

2,5-Dihydrofurandione,Isobutenyl Deriv/Polyethylene Glycol is a specialized functionalized polymer, specifically a maleic anhydride derivative grafted with a polyethylene glycol chain via an isobutenyl linker. This unique structure provides a versatile platform chemical with reactive anhydride groups and hydrophilic PEG segments, enabling its use as a key intermediate for synthesizing advanced materials. It is primarily sought by formulators and researchers in the pharmaceutical, personal care, and specialty polymer industries for applications requiring biocompatibility, controlled reactivity, or tailored surface properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of polymer-drug conjugates for controlled release and targeted delivery systems.
• Biomaterial Modification: Serves as a grafting agent to impart hydrophilicity and biocompatibility to surfaces of medical devices or implants.
• Personal Care Formulations: Acts as a reactive modifier in hair care and skincare products to create film-forming polymers with enhanced conditioning properties.
• Specialty Polymer Synthesis: A key monomer for producing water-soluble or amphiphilic copolymers used in dispersants, superplasticizers, and coatings.
• Crosslinking Agent: Utilized in the preparation of hydrogels and crosslinked networks for biomedical and agricultural applications.
• Surface Active Agent: Functions as a reactive surfactant or emulsifier in advanced emulsion and dispersion formulations.

Quality Control

Every batch of our 2,5-Dihydrofurandione,Isobutenyl Deriv/Polyethylene Glycol is manufactured under a strict quality management system. We ensure consistent performance through rigorous in-process and final product testing, which includes analysis of functional group content, molecular weight distribution, and purity. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature hydrolysis of the anhydride functionality.
