I. [Product Description]
SH-PEG-TK-SH (Thiol-Polyethylene Glycol-TK-Thiol) is a multifunctional organic intermediate with both high catalytic activity and molecular designability. It is widely used in the fields of polymer material synthesis and bioconjugation. The thiol groups (-SH) at both ends can achieve controllable assembly and dissociation through dynamic disulfide bonds. The TK (Thioketal) structure endows it with excellent chemical stability. Combining the hydrophilicity and biocompatibility of the PEG chain, it is an ideal choice for constructing intelligent responsive materials.
