Biotin-PEG3-acid is a biotin-labeled PEG linker with a terminal carboxylic acid group designed for use in bioconjugation and PROTAC synthesis. It provides a short, hydrophilic PEG3 spacer to improve solubility and reduce steric hindrance while enabling affinity capture or detection via the biotin tag.

  • Biotin-labeled PEG3 spacer for affinity capture and detection.
  • Terminal carboxylic acid enables straightforward amide coupling to amine-containing partners.
  • Hydrophilic PEG spacer improves solubility and linker flexibility.
  • Analytical data available (molecular weight 447.55, molecular formula C19H33N3O7S).
  • Supplied as a solid for research use, available in gram-scale quantities.
