Medchemexpress LLC Propargyl-PEG1-bromide | 18668-74-1 | MFCD00099299 | 98.0% | 163.01 g/mol | C5H7BrO | 100 MG
Propargyl-PEG1-bromide is a short polyethylene glycol (PEG) derivative bearing a terminal propargyl (alkyne) group and a bromide leaving group. It is used as a reactive linker in synthetic and chemical biology workflows where a minimal PEG spacer and an alkyne handle enable conjugation and further functionalization. Typical applications include click chemistry, bioconjugation, and assembly of drug-delivery constructs.
- Contains a terminal propargyl (alkyne) functional group for click reactions.
- Contains a bromide leaving group for nucleophilic substitution.
- One-unit PEG spacer provides improved solubility with low steric bulk.
- Enables copper-catalyzed azide-alkyne cycloaddition (click chemistry).
- Suitable for linker synthesis, bioconjugation, and drug-delivery research.
- Small molecular weight and compact linker length for precision conjugation.
