Biopharma PEG provides high purity Boc-NH-PEG2-OH (N-Boc-PEG2-alcohol), a PEG linker containing a Boc protected amine (NH2) group and a terminal hydroxyl(OH) group. The Boc protecting group can be removed under acidic conditions. The hydroxyl group can react to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of the compound.

Boc-NH-PEG2-OH (PROTAC Linker 11) can be used in the synthesis of a series of PROTACs.
