Cl-PEG2-acid features a chloro-functionalized terminus on a short-chain PEG spacer, enabling selective conjugation with nucleophilic amines. This bifunctional architecture combines the solubility and stability of PEGylation with reactive halogen chemistry, streamlining the attachment of peptides, proteins, or small molecules in bioconjugation workflows under mild conditions.
Cl-PEG2-acid serves as a versatile bifunctional linker for conjugation and polymer synthesis, combining the robustness of a chloroalkyl activation site with a terminal carboxylic acid. It enables efficient coupling to amine-containing biomolecules or resins under mild conditions, while its PEG2 spacer enhances solubility and reduces non-specific binding. Ideal for drug delivery systems and diagnostic probes, it offers reliable stability, straightforward purification, and compatibility with standard synthetic workflows.
