Description

3,6,9,12,15-Pentaoxaoctadec-17-En-1-Ol is a high-purity polyethylene glycol (PEG) derivative featuring a terminal hydroxyl group and an unsaturated alkene moiety. This unique bifunctional structure makes it a valuable reactive intermediate for the synthesis of specialized polymers, surfactants, and functional materials. It is particularly sought after by R&D and production teams in the pharmaceutical, advanced materials, and specialty chemical industries for creating custom-tailored compounds with specific solubility, biocompatibility, or cross-linking properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, PEGylated therapeutics, and drug delivery systems to enhance solubility and bioavailability.
• Polymer Modification: Serves as a macromonomer or cross-linker for creating hydrogels, responsive polymers, and biocompatible coatings.
• Specialty Surfactant Synthesis: Acts as a key building block for producing non-ionic surfactants and emulsifiers with tailored hydrophilic-lipophilic balance (HLB).
• Bioconjugation: Utilized for attaching polyethylene glycol chains (PEGylation) to proteins, peptides, or other biomolecules to improve stability and reduce immunogenicity.
• Material Science: Incorporated into formulations for advanced lubricants, plasticizers, and surface treatment agents.
• Research & Development: A versatile reagent for academic and industrial research in organic synthesis and macromolecular engineering.

Quality Control

Our 3,6,9,12,15-Pentaoxaoctadec-17-En-1-Ol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure it meets the high standards required for sensitive applications. Certificates of Analysis (COA) are provided with each shipment, detailing all relevant specifications and test results.

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 an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and potential degradation.
