BPG-0989 4-Arm PEG-Alkyne, MW 2k-20k Inquiry

Each of the 4-Arm PEG-Alkyne has an alkyl or acetylene group attached to a pentaerythritol core at the end of each arm. It is a multi-armed PEG derivative. It is sold as a product with an amount of inhibitor added. 4-Arm PEG-Alkyne's total molecular weight is the sum of the molecular weights of all the arms. 4-Arm PEG-Alkyne can used for PEGylation via a copper-catalyzed click chemistry reaction with azide. Multi-armed PEG derivatives are commonly used in drug delivery systems. The increased molecular weight of the modified drug is not easily eliminated by metabolism in the body. In addition, the dispersibility and solubility of the modified drug in the body will be improved. Multi-armed PEG derivatives can also modify the surface of biological materials or form new biomedical materials.
