Hydroxy-PEG2-acid is a bifunctional PEG-based reagent featuring a terminal hydroxyl group and a carboxylic acid moiety. This dual functionality enables site-specific conjugation in bioconjugation workflows, offering enhanced solubility and stability in aqueous environments. The short PEG spacer provides controlled spacing with minimal steric interference.
Hydroxy-PEG2-acid serves as a versatile bifunctional linker for conjugation and solubilization in synthetic chemistry. Its hydroxyl group enables derivatization or coupling reactions, while the terminal carboxylic acid facilitates amide bond formation with amines under standard conditions. The PEG2 spacer provides enhanced solubility and reduced aggregation, making it ideal for applications in bioconjugation, peptide modification, and the construction of functionalized polymers.
