Amino-PEG-alcohol(Amino-PEG-OH) is a type of compound that consists of a polyethylene glycol (PEG) backbone, an amino group, and an alcohol group. This functional group arrangement allows for a variety of chemical modifications, making it a useful tool in pharmaceutical research and development. Amino-PEG-alcohol can be used as a linker to attach drugs or other molecules to targeting agents such as antibodies or peptides. It can also be used to modify the surface of nanoparticles for drug delivery, increasing their biocompatibility and reducing toxicity. Additionally, the presence of the amino group makes Amino-PEG-alcohol useful for conjugation with biomolecules such as proteins or DNA.
