m-PEG4-CH2COOH features a methoxy-terminated PEG chain of four ethylene oxide units linked to a methylene carboxylic acid group. This structure delivers enhanced solubility in aqueous and organic media, enabling efficient conjugation workflows. The terminal carboxylate facilitates direct coupling to primary amines under standard activation conditions.
m-PEG4-CH2COOH serves as a versatile bifunctional linker for conjugation and polymer synthesis, combining the stability of a methoxy-terminated PEG chain with a reactive carboxylic acid group. It facilitates efficient coupling to amine-containing biomolecules or resins under standard EDC/NHS conditions, enabling controlled spacing in bioconjugates and functionalized surfaces. The PEG4 spacer provides enhanced solubility and reduced non-specific binding in aqueous environments, making it ideal for applications in medicinal chemistry, diagnostic labeling, and materials science.
