4-Arm-PEG5000-Benzaldehyde 

4-Arm-PEG5000-Benzaldehyde is a four-armed PEG derivative. The core structure of 4-Arm-PEG5000-Benzaldehyde consists of four PEG chains, each modified at the end with a benzaldehyde group. 4-Arm-PEG5000-Benzaldehyde can be used for bioconjugation and drug delivery.

The structure of PEG-Benzaldehyde comprises two key parts that work synergistically:
Benzaldehyde group: Possesses a reactive aldehyde group (–CHO), capable of undergoing condensation reactions with various amino-containing compounds (such as amines, hydroxylamines, etc.) to form imine or oxime bonds.
PEG chain: Acts as a hydrophilic spacer, forming a hydration layer on the particle surface, which can reduce non-specific adsorption and recognition and clearance by the immune system, prolonging the carrier's circulation time in vivo.
