PEG3（Cat No.:I044717）, or triethylene glycol, is a short-chain polyethylene glycol consisting of three ethylene glycol units. It is widely used as a hydrophilic linker in pharmaceuticals, bioconjugation, and materials science due to its excellent water solubility and flexibility. PEG3 enhances the solubility, stability, and biocompatibility of conjugated molecules, reducing aggregation and immunogenicity. It serves as a spacer in drug delivery systems, enabling better spatial orientation and accessibility of functional groups. PEG3 is also used in surface modification, diagnostics, and polymer synthesis, supporting a broad range of biomedical and chemical research applications.
