Br-PEG3-CH2COOtBu is a brominated polyethylene glycol (PEG) compound that is commonly used in pegylation processes. Pegylation involves the covalent attachment of PEG to a target molecule, such as a protein or drug, to enhance its stability, solubility, and circulation time in the body. Br-PEG3-CH2COOtBu serves as a PEG linker, providing a bridge between the target molecule and the PEG chain. The bromine moiety in Br-PEG3-CH2COOtBu allows for specific and controlled pegylation reactions. It enables the attachment of PEG to reactive groups on the target molecule, forming stable bonds. This brominated PEG compound is widely used in the synthesis of various pegylated products for pharmaceutical, biotechnological, and research applications. Br-PEG3-CH2COOtBu offers several advantages in pegylation processes. Its halogenated nature provides high reactivity

Bromo-PEG3-CH2-Boc is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules.
