Description
Benzyl-PEG7-alcohol features a hydrophilic PEG7 chain terminating in a primary alcohol, enabling conjugation or derivatization. The benzyl group enhances solubility and stability in organic solvents, making it ideal for synthesizing bioconjugates, drug delivery systems, and functionalized surfaces under standard conditions.
Application
Benzyl-PEG7-alcohol serves as a versatile, bench-stable linker for the synthesis of bioconjugates and functionalized polymers. Its terminal hydroxyl group enables straightforward derivatization via esterification or etherification, while the PEG7 spacer provides enhanced solubility and reduced aggregation. The benzyl moiety offers orthogonal protection and facilitates purification through standard chromatographic techniques. This compound functions effectively in peptide modification, drug delivery systems, and surface functionalization workflows.
