THP-PEG2-bromide
This product is a heterobifunctional PEG linker containing a tetrahydropyranyl (THP) protecting group, a PEG2 spacer, and a terminal bromide. The bromide functions specifically as an excellent leaving group, enabling nucleophilic substitution with amines, thiols, or alkoxides. The THP group protects hydroxyl functionality for controlled deprotection, while the PEG2 spacer enhances solubility and flexibility. This compact design makes it an especially useful intermediate for bioconjugation and synthesis.
