Bis-PEG2-acid features two carboxylic acid termini linked by a short, hydrophilic PEG2 spacer. This bifunctional molecule enables site-specific conjugation in aqueous environments, offering enhanced solubility and stability for bioconjugation workflows.
Bis-PEG2-acid serves as a versatile bifunctional linker for conjugation and polymer synthesis, enabling efficient coupling to amines or activated esters under mild conditions. Its two PEG2 spacers provide enhanced solubility and reduced steric hindrance, while the terminal carboxylic acids offer high reactivity in standard amide bond formation. Ideal for building bioconjugates, drug delivery systems, and functionalized surfaces with improved hydrophilicity and stability.
