Boc-NH-PEG2-OH (2-(2-Boc-aminoethoxy)ethanol, CAS: 139115-91-6) is a short PEG linker that includes a Boc-protected amine and a terminal hydroxyl group. The PEG2 spacer provides increased water solubility, making it suitable for applications in bioconjugation and drug delivery. The hydroxyl group allows for further chemical modifications, while the Boc group can be deprotected under mild acidic conditions to yield a free amine, enabling additional functionalization. Boc-NH-PEG2-OH is a valuable cross-linking reagent for creating stable, targeted linkages in advanced synthesis and molecular engineering projects.

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