Amino-PEG1-C2-acid features a terminal amine and carboxylic acid group separated by a short ethylene glycol chain, enabling dual conjugation versatility. This bifunctional linker supports efficient coupling to biomolecules or surfaces via amine- or carboxyl-reactive chemistries. The PEG spacer enhances solubility and reduces non-specific binding in biological applications.
Amino-PEG1-C2-acid serves as a versatile bifunctional linker for conjugation and polymer synthesis. The primary amine enables efficient coupling to carboxylate- or aldehyde-functionalized substrates, while the terminal carboxylic acid facilitates amide bond formation or activation with common coupling reagents. Its PEG1 spacer provides moderate hydrophilicity and solubility in aqueous and organic media, enhancing compatibility in bioconjugation workflows. The molecule exhibits excellent bench stability and simplifies purification by enabling selective derivatization under standard conditions.
