I. [Product Description]
CHO-PEG-SH (Aldehyde-Polyethylene Glycol-Thiol) is a bifunctional PEG derivative that combines the high reactivity of aldehyde and thiol groups. It can serve as an organic intermediate or a pharmaceutical intermediate and is widely used in the fields of bioconjugation, material modification, and catalyst support. The PEG chain in its molecular structure endows it with excellent water solubility and biocompatibility, making it suitable for the design of directional conjugation and stabilization in complex systems.

III. [Application Areas]
1. Biomolecule Conjugation: The aldehyde group reacts specifically with amino groups, and the thiol group is used for the immobilization on gold nanoparticles or thiol-modified surfaces.
2. Nanomaterial Modification: It serves as a bifunctional cross-linking agent to prepare functionalized nanocarriers.
3. Polymer Material Synthesis: Construct intelligent hydrogels through the thiol-ene click chemical reaction.
4. Catalyst Support Construction: Load metal catalysts to improve the dispersibility and cycle stability of the catalytic system.
5. Surface Coating Modification: Used for the directional functional modification of the surface of biosensors.
