Description

Propargyl-PEG7-alcohol offers a linear, hydrophilic PEG spacer with a terminal alkyne for bioconjugation and a primary alcohol for further functionalization. This bifunctional architecture enables site-specific coupling via click chemistry while maintaining solubility in aqueous and organic media. The molecule’s stability under standard conditions supports reliable use in probe synthesis and biomolecule labeling workflows.

Application

Propargyl-PEG7-alcohol serves as a versatile, bench-stable linker for bioconjugation and polymer chemistry. Its terminal alkyne enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), while the PEG7 spacer provides solubility and reduced non-specific binding. The primary alcohol facilitates further functionalization or derivatization. This reagent is compatible with standard synthetic workflows and offers predictable conjugation efficiency in peptide, oligonucleotide, and nanoparticle modifications.
