Description

m-PEG3-benzaldehyde features a three-atom polyethylene glycol spacer linking a terminal aldehyde group to a para-substituted phenyl ring. This structure enables efficient conjugation in bioorthogonal reactions and facilitates solubility in aqueous and organic media. The aldehyde moiety serves as a reactive handle for site-specific protein labeling or polymer functionalization under mild conditions.

Application

m-PEG3-benzaldehyde serves as a versatile bifunctional building block for conjugation and polymer synthesis, combining the stability of a methoxy-terminated PEG chain with a reactive aldehyde group. It enables efficient amine coupling under mild conditions, facilitates purification via precipitation or chromatography, and functions reliably in the construction of targeted molecular architectures, including drug conjugates and functionalized surfaces.
