m-PEG12-acid features a linear polyethylene glycol chain of 12 ethylene oxide units terminating in a carboxylic acid group. This amphiphilic architecture enables solubility in aqueous and polar organic solvents, facilitating conjugation workflows. The terminal acid group supports direct coupling to amine-functionalized biomolecules or surfaces via standard amidation protocols.
m-PEG12-acid serves as a versatile, bench-stable linker for conjugation chemistry, enabling efficient attachment of functional groups via amide bond formation. Its linear PEG spacer provides enhanced solubility and reduced aggregation in aqueous environments, while the terminal carboxylic acid facilitates straightforward coupling with amines under standard activation conditions. Widely used in bioconjugation and polymer chemistry, it supports modular synthesis of targeted molecular architectures with predictable physicochemical properties.
