Description

Tr-PEG3-OH is a trifunctional polyethylene glycol derivative featuring three PEG3 chains radiating from a central core. This structure provides enhanced solubility and steric shielding, ideal for conjugation applications requiring prolonged circulation and reduced aggregation in biological environments.

Application

Tr-PEG3-OH serves as a versatile, bench-stable linker for conjugation and functionalization workflows. The triethylene glycol (PEG3) spacer provides enhanced solubility and reduced aggregation, while the terminal hydroxyl group enables straightforward derivatization via esterification, etherification, or activation for amide coupling. Its well-defined structure facilitates reproducible synthesis in peptide, oligonucleotide, and macrocyclic compound assembly.
