Biotin-PEG-Boc

Biotin-PEGn-CH₂CH₂NHBoc is primarily used as a protected intermediate in organic synthesis, where the Boc group safeguards the amine during bioconjugation until acidic deprotection. Its key benefits include the versatile PEG spacer for solubility and reduced steric hindrance, and the orthogonally protected amine which enables controlled, multi-step bioconjugation strategies.
