Bis-PEG4-acid features two carboxylic acid termini flanking a central PEG4 spacer, enabling efficient conjugation in aqueous environments. This bifunctional linker combines excellent solubility with stability under standard bench conditions, facilitating robust coupling reactions in biomolecule labeling and polymer synthesis.
Bis-PEG4-acid serves as a versatile bifunctional linker for conjugation and polymer synthesis, offering excellent solubility and stability in aqueous and organic media. Its two terminal carboxylic acid groups enable efficient coupling with amines via amide bond formation, while the PEG4 spacer provides enhanced solubility and reduced non-specific binding. Widely used in bioconjugation, drug delivery systems, and surface functionalization, it facilitates precise spatial control and improved pharmacokinetic properties in advanced molecular architectures.
