Bis-PEG4-TFP ester（Cat No.:I044707）is a bifunctional reagent commonly used in peptide conjugation and drug delivery applications. It consists of two PEG4 (polyethylene glycol) linkers, which enhance solubility and biocompatibility, connected to a TFP (2,3,4,5-tetrafluorophenyl) ester group. The TFP ester group is highly reactive, allowing for efficient coupling with amine-containing molecules, such as peptides, proteins, or other biomolecules. This compound is ideal for creating stable, water-soluble conjugates, improving the pharmacokinetics and targeting capabilities of therapeutic agents, especially in drug delivery systems for oncology and other disease treatments.
