Br-PEG6-CH2CH2COOtBu is a halogenated PEG compound that is commonly used in pegylation processes. Pegylation refers to the covalent attachment of polyethylene glycol (PEG) to a molecule, which can enhance its stability, solubility, and pharmacokinetic properties. This heterobifunctional PEG product contains a bromine atom, making it suitable for specific applications that require the presence of a bromo group. Br-PEG6-CH2CH2COOtBu serves as a versatile PEG linker, allowing for the conjugation of various molecules or biomolecules. Its brominated structure provides an additional reactive site for further functionalization or modification. The t-butyl ester group at one end of the molecule offers protection during synthesis and can be easily removed under mild conditions to expose the carboxylic acid functionality. With its unique characteristics, Br-PEG6-CH2CH2COOtBu is an essential

Bromo-PEG6-Boc is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules.
