Applications & Uses
Description
Amino-PEG8-Amine is a conjugation linker containing two amine (NH2) groups. The hydrophilic PEG spacer increases solubility in aqueous media. The amino groups are reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc.
Uses
Amino-PEG8-amine is a PEG-based (8 units) PROTAC linker can be used in the synthesis of PROTACs[1].
Uses
Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization
General Description
Amino-PEG8-amine (CAS 82209-36-7), also known as H₂N-PEG8-CH₂CH₂NH₂ and NH₂-PEG8-NH₂, is a high-purity, symmetrical, homobifunctional, discrete PEG linker. Its molecular weight is 412.52. It is soluble in water, DMSO, DCM and DMF. At room temperature, it is typically a pale yellow to colourless viscous liquid or a low-melting-point waxy solid.
