I. [Product Description]
SH-PEG-His (Thiol-Polyethylene Glycol-Histidine) is a multifunctional organic intermediate that combines the hydrophilicity of the PEG chain, the coupling activity of the thiol group, and the metal coordination ability of histidine. It is widely used in the fields of bioconjugation, catalyst carriers, and polymer material modification. Its structure is flexibly designed and can be used as a pharmaceutical intermediate or a functional modifier, significantly enhancing the stability and biocompatibility of the complex.

III. [Application Fields]
    1. Surface modification of nanomaterials: Utilize the strong binding ability of the thiol group to the surface of metals/semiconductors to achieve functional modification.
    2. Development of biosensors: The metal chelation property of histidine is used to immobilize enzymes or labeled molecules.
    3. Construction of catalyst carriers: Regulate the dispersibility of the catalytic active center through the solubility of the PEG chain.
    4. Modification of polymer materials: Introduce PEG to enhance the hydrophilicity and anti-protein adsorption performance of the materials.
    5. Conjugation of proteins/peptides: The thiol group specifically reacts with cysteine residues to achieve directional labeling.
