S-acetyl-PEG4-amine TFA（Cat No.:I042843）is a compound consisting of a polyethylene glycol (PEG) chain with a terminal amine group, modified with an acetyl group, and typically used in research and drug development. The acetylation stabilizes the compound, enhancing its solubility and bioavailability. PEGylation, the process of attaching PEG to a molecule, improves pharmacokinetics by increasing stability and reducing immunogenicity. S-acetyl-PEG4-amine TFA is often employed in the synthesis of conjugates, such as drug-delivery systems, peptide formulations, or targeting agents, and is used in bioconjugation applications for therapeutic and diagnostic purposes.
