Description

3,6,9,12,15,18,21,24,27,30,33,36-Dodecaoxaoctatriacontane-1,38-Diol is a high-purity polyethylene glycol (PEG) derivative, specifically a long-chain PEG diol, valued for its exceptional hydrophilicity, biocompatibility, and ability to modify the physicochemical properties of other materials. This compound is a critical building block in advanced material science and pharmaceutical development, where precise control over molecular architecture is paramount. It is primarily needed by researchers and manufacturers in the pharmaceutical, biotechnology, and specialty polymer industries for applications ranging from drug delivery systems to surface functionalization.

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 hydrophilic crosslinker or component in the synthesis of hydrogels for tissue engineering, wound dressings, and controlled-release matrices.
• Surface Modification: Employed to create non-fouling, protein-resistant coatings on medical devices, sensors, and diagnostic platforms to improve biocompatibility.
• Polymer Synthesis: Acts as a macroinitiator or monomer in the production of block copolymers, dendrimers, and other advanced polymeric structures with tailored properties.
• Analytical Chemistry: Utilized as a standard or reagent in chromatographic methods and for calibrating instruments due to its well-defined molecular weight.
• Cosmetic Formulations: Incorporated as a humectant and stabilizer in high-performance skincare products to improve texture and delivery of active ingredients.
