NH2-PEG8-NH2 (Amino-PEG8-Amine, CAS: 82209-36-7) is a versatile PEG-based linker featuring two amino groups. This structure provides a hydrophilic spacer that enhances solubility in aqueous solutions. The amino groups on NH2-PEG8-NH2 are highly reactive with various functional groups, including carboxylic acids, activated NHS esters, and carbonyls (such as ketones and aldehydes). This reactivity makes it an effective tool for conjugation and crosslinking applications, facilitating the formation of stable bonds in bioconjugates, drug delivery systems, and other PEGylated compounds.
