Boc-NH-PEG2-N3 (t-Boc-N-Amido-PEG2-Azide, CAS: 950683-55-3) is a highly functional PEG linker designed for advanced bioconjugation and drug development applications. This compound features an azide group and a Boc-protected amine, connected by a PEG3 spacer that enhances solubility in aqueous media. The azide group is reactive with alkyne, BCN, and DBCO groups via Click Chemistry, forming a stable triazole linkage ideal for creating robust molecular connections. The Boc group can be easily removed under mild acidic conditions to reveal a free amine, enabling further amide coupling with carboxylic acid-containing biomolecules. This dual-functional linker is an excellent choice for clients seeking reliable and efficient tools for targeted biomolecule modification and drug delivery projects.
