azide peg azide (mw 20000)

Azide-PEG-azide (MW 20000) is a polyethylene glycol (PEG)-based linker compound used in the synthesis of Proteolysis Targeting Chimeras (PROTACs)[1].

m-PEG-azide (MW 20000) is a PEG-based linker for PROTACs, facilitating the connection of two essential ligands necessary for forming PROTAC molecules, thereby enabling selective protein degradation through the ubiquitin-proteasome system within cells.

N3-PEG-SCM (MW 20000) (Azide PEG Succinimidyl Carboxymethyl Ester (MW 20000)) is a linear PEG product with heterobifunctional groups, featuring both an azide group and a succinimidyl carbonate moiety.

4-Arm PEG-Azide (MW 20000) [4-Arm PEG-N3 (MW 20000)] is a multi-arm polyethylene glycol derivative with azide groups at the ends of its four arms, connected to a pentaerythritol core.

DBCO-PEG-Biotin (MW 20000) is a click chemistry biotin conjugate that reacts with azide molecules through copper-free click chemistry, resulting in the formation of stable triazole bonds.

N3-PEG-NH2 (MW 20000) (Azide-PEG-Amine (MW 20000)) is a heterobifunctional PEG compound characterized by azide and amine groups located at the termini of the PEG chain. Serving as a significant crosslinking agent with a PEG backbone, the azide component facilitates molecular conjugation through chemical reactions, while the amine group is reactive with carboxylic acids or NHS esters.

mPEG-Alkyne (MW 20000) is a PEG derivative. Under the catalysis of a monovalent copper, the alkyne group can chemically react with azide in an aqueous solution. Polyethylene glycol derivatives enhance drug solubility and stability, reduce peptide immunogenicity, and exhibit excellent biocompatibility.
