    Thiol-PEG-Azide (or Azide-PEG-Thiol) is a heterobifunctional polyethylene glycol (PEG) linker with terminal thiol (-SH) and azide (-N₃) groups. Its design allows for versatile applications in bioconjugation and materials science.

    Key Features:

    • Functional Groups: Thiol (-SH) and azide (-N₃)
    • PEG Spacer: Provides flexibility and improves solubility
    • Solubility: Compatible with water, ethanol, chloroform, and DMSO

    Applications:

    1. Click Chemistry:
      • The azide group reacts with alkynes in click reactions to form stable triazoles.
    2. Bioconjugation:
      • The thiol group enables reactions with maleimides or the formation of disulfide bonds for biomolecule attachment.
    3. Surface Modification:
      • The thiol group binds to metal surfaces, such as gold, for functionalizing nanoparticles or biosensors.

    Thiol-PEG-Azide is a versatile reagent for creating advanced molecular structures and functionalized surfaces.
