NH2-PEG5-NH2 (Amino-PEG5-Amine, CAS: 72236-26-1) is a PEG derivative with two amino groups. The amino groups provide reactivity with various functional groups, including carboxylic acids, activated NHS esters, and carbonyls (such as ketones and aldehydes). This structure makes NH2-PEG5-NH2 particularly useful as a crosslinker or coupling agent in biochemical and pharmaceutical applications. It facilitates the formation of stable linkages in the synthesis of bioconjugates, drug delivery systems, and other PEGylated products, enhancing solubility and stability in aqueous environments.
