Description

α-Methyl-ω-[(Tetrahydro-2-Furanyl)Methoxy]-Poly[Oxy (Methyl-1,2-Ethanediyl)] is a specialized polyether derivative, known for its unique terminal functionalization with a tetrahydrofuran moiety. This compound is valued for its role as a versatile polymeric intermediate and functional additive, offering tunable properties based on its polyoxyethylene chain length. It is primarily sought after by formulators and researchers in the pharmaceutical, advanced materials, and specialty chemical industries for applications requiring precise polymer architecture and surface modification.

Application

• Pharmaceutical Excipient: Used as a solubilizer, bioavailability enhancer, or a component in drug delivery systems for poorly soluble active pharmaceutical ingredients (APIs).
• Polymer Modification: Acts as a macromonomer or chain transfer agent in the synthesis of block and graft copolymers with tailored hydrophilic-lipophilic balance (HLB).
• Surface-Active Agent: Employed in the formulation of specialty surfactants, dispersants, and emulsifiers for high-performance coatings and inks.
• Chemical Intermediate: Serves as a key building block for further chemical reactions, leveraging its reactive terminal hydroxyl group for conjugation.
• Material Science: Incorporated into hydrogels, resins, and other polymeric matrices to modify flexibility, compatibility, and degradation profiles.
