QTMA-Cl-PEG-DMA

Quaternary ammonium chloride-poly(ethylene glycol)-N,N-Ditetradecylacetamide (QTMA-Cl-PEG-DMA) is an amphiphilic PEG lipid combining a di-C14 alkyl amide anchor with a defined-length hydrophilic PEG segment. Discrete chain lengths with different degrees of polymerization are available. The quaternary ammonium terminus provides a fixed cationic site, allowing terminal charge and PEG chain length to be studied separately and paired with anionic components. It can be used to construct interfaces in membrane-related systems and nanoparticle formulations, enabling comparisons of anchoring structure, hydrophilic chain length, terminal functionality, and formulation dispersion.
