Br-PEG4-NH-Boc is a versatile PEG linker featuring a bromide group and a Boc-protected amino group. The hydrophilic PEG spacer enhances solubility in aqueous media, while the bromide serves as an excellent leaving group for nucleophilic substitution reactions. The Boc group can be easily removed under mild acidic conditions, yielding a free amine for further functionalization.

Biological Applications
Br-PEG4-NH-Boc functions as a PROTAC linker within the PEG and alkyl/ether classes, enabling the synthesis of diverse PROTAC molecules. Additionally, it serves as a cleavable ADC linker, playing a crucial role in the development of antibody-drug conjugates (ADCs) for targeted therapeutic applications.
