Dodecaethylene Glycol丨CAS 6790-09-6

Dodecaethylene glycol is a high-molecular-weight polyethylene glycol (PEG) compound widely used in pharmaceutical, biochemical, and materials science applications. Its multiple ethylene glycol units provide excellent solubility in water and organic solvents, making it suitable for use as a linker, spacer, or stabilizer in drug delivery systems, protein and peptide conjugation, and polymer modification. It is also employed in the synthesis of PEGylated therapeutics, hydrophilic coatings, hydrogels, and functionalized polymers, where the long PEG chain enhances flexibility, solubility, and biocompatibility. Additionally, dodecaethylene glycol is used in surface modification, nanomaterials, and as a solvent or additive in organic synthesis requiring high polarity and low toxicity.

The benefits of dodecaethylene glycol derive from its high water solubility, chemical stability, and biocompatibility. Its long PEG chain reduces aggregation, improves dispersion, and minimizes immunogenicity in biomedical applications. The compound's flexibility allows it to act as an effective linker or spacer in conjugated systems, enhancing accessibility and activity of attached biomolecules. It is non-toxic, chemically stable, and compatible with both aqueous and organic reaction conditions, making it suitable for multi-step syntheses and industrial processes. Its ability to improve solubility, stability, and functional performance makes it a highly versatile ingredient in pharmaceuticals, biomaterials, and chemical formulations.
