Cas no 139115-92-7 (Boc-NH-PEG3)
Boc-NH-PEG3 is a polyethylene glycol (PEG)-based linker featuring a Boc-protected amine group and a triethylene glycol spacer. This compound is widely used in bioconjugation and peptide synthesis due to its hydrophilic PEG backbone, which enhances solubility and reduces aggregation in aqueous systems. The Boc group provides selective protection for the amine functionality, enabling controlled deprotection under mild acidic conditions. Its three-unit PEG spacer offers flexibility and optimal spacing for coupling reactions, making it suitable for applications in drug delivery, protein modification, and material science. The compound’s stability and compatibility with standard synthetic protocols further contribute to its utility in diverse chemical and biochemical workflows.
