N-Boc-N-bis(PEG2-OH)(CAT: I017218) is a versatile PEG-based bifunctional linker commonly used in peptide synthesis, PROTAC design, and bioconjugation chemistry. It features a Boc-protected amine group that provides orthogonal protection for controlled synthetic strategies, while two PEG2-hydroxyl arms enhance solubility, flexibility, and reduce steric hindrance during conjugation. This structure makes N-Boc-N-bis(PEG2-OH) well-suited for preparing multifunctional molecules, including drug-linker conjugates, targeted delivery systems, and PEGylated biomolecules. Its modular design supports applications in chemical biology, medicinal chemistry, and materials science, enabling efficient construction of complex architectures with improved pharmacokinetic and physicochemical properties.
