Description

3,6,9,12,15,18,21,24,27,30,33,36,39-Tridecaoxahentetracontane-1,41-Diol is a high-purity, long-chain polyethylene glycol (PEG) derivative, specifically a PEG-1000 diol, valued for its exceptional hydrophilicity and ability to modify surface properties. This compound is a critical building block in advanced material science, where it provides controlled solubility, biocompatibility, and non-fouling characteristics. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and specialty polymer industries seeking to create functionalized materials.

Application

• Pharmaceutical Conjugation: Used as a linker or spacer arm in the PEGylation of proteins, peptides, and small molecule drugs to enhance solubility, reduce immunogenicity, and prolong circulation half-life.
• Biomaterial Fabrication: Serves as a key monomer for synthesizing hydrogels, coatings, and scaffolds that require high water content and resistance to protein adsorption.
• Surface Modification: Applied to create hydrophilic, non-fouling surfaces on medical devices, sensors, and membranes to prevent biofouling and improve performance.
• Polymer Synthesis: Acts as a macro-initiator or telechelic diol for producing block copolymers, polyurethanes, and other segmented polymers with tailored properties.
• Cosmetic Formulations: Employed as a humectant and moisturizing agent in high-performance skincare products due to its water-binding capacity.
• Lubricants & Functional Fluids: Utilized in the formulation of specialized, water-soluble lubricants and heat transfer fluids.
