Propargyl bromide, 80% in toluene is used to prepare betulonic acid-peptide conjugates with anti-inflammatory activity and propargylic amines employed in enyne metathesis. It finds application in the propargylation of spiro ketones, allylic alcohols and enone complexes. In Barbier-type reaction, it reacts with aldehydes to give alkyne alcohols. It is actively involved in the synthesis of polyethylene glycol (PEG) and peptide-grafted polyesters.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
