Amino-PEG9-alcohol(CAT: I016805) is a heterobifunctional PEG linker containing a terminal primary amine and a terminal hydroxyl group, separated by a PEG9 spacer. The amine group enables versatile conjugation through amide bond formation with activated esters such as NHS esters or carboxylic acids, while the hydroxyl group offers an additional handle for further chemical modification. The PEG9 chain enhances solubility, reduces steric hindrance, and provides flexibility, improving conjugation efficiency. With dual functionality, Amino-PEG9-alcohol is a useful intermediate in preparing custom linkers, polymers, and biomolecular conjugates. It is widely applied in chemical biology, drug delivery, and materials science research.
