Medchemexpress LLC Propargyl-PEG1-bromide | 18668-74-1 | MFCD00099299 | 98.0% | 163.01 | C5H7BrO | 1 G
Supplier: Medchemexpress LLC HYW1908051G
Propargyl-PEG1-bromide is an alkyne-functionalized short polyethylene glycol (PEG) linker bearing a terminal bromide. It is used in bioconjugation and medicinal chemistry to introduce a clickable propargyl handle while providing a reactive leaving group for further substitution, enabling efficient incorporation of a short PEG spacer into synthetic linkers and small-molecule constructs.
- Provides an alkyne (propargyl) handle for click chemistry.
- Contains a terminal bromide for nucleophilic substitution reactions.
- Short PEG1 spacer improves solubility and minimizes steric hindrance.
- Molecular weight ~163.01 g/mol for predictable stoichiometry.
- Suitable for linker synthesis, bioconjugation, and small-molecule modification.
