I. [Product Description]
OH-PEG-TK-OH is an organic intermediate modified based on polyethylene glycol (PEG), which has both excellent water solubility and biocompatibility. It can be used as a pharmaceutical intermediate or a catalyst carrier. Its core value lies in achieving efficient coupling through the active site of the TK (tyrosine kinase) group. Meanwhile, the PEG segment endows the molecule with an adjustable molecular weight and stability, making it suitable for various functionalization reaction systems.
