Boc-NH-PEG10-NHS ester(CAT: I045968) is a heterobifunctional PEG reagent featuring a Boc-protected amine and an N-hydroxysuccinimide (NHS) ester separated by a PEG10 spacer. The NHS ester enables efficient conjugation to primary amines on proteins, peptides, or other biomolecules, while the Boc group serves as a removable protective functionality for subsequent modification. The PEG10 chain enhances hydrophilicity, flexibility, and molecular spacing, reducing steric hindrance and non-specific interactions. This reagent is widely used in bioconjugation, drug delivery research, and surface modification, supporting the development of advanced biomedical materials where controlled PEGylation improves solubility, stability, and functional versatility in complex chemical and biological systems.
