General description

The product is 80% solution of propargyl bromide in toluene. Propargyl bromide (3-bromopropyne, C3H3Br, or 3BP) possess propargyl group, which is an important three-carbon building block. It participates in the stereoselective propargylation reaction of α-alkoxy aldehydes. It is used to compose a soil fumigant trizone.

Application

Propargyl bromide solution may be used in the synthesis of the following:
  • new arabinogalactan propargyl ethers with degree of substitution (DS) up to 2.8, by propargylation of arabino-3,6-galactan
  • conjugated polyelectrolyte with polyacetylene as the backbone and pyridinium as side groups, poly(propargyl pyridinium bromide)
  • benzodiazepine derivative, 4-phenyl-1-(prop-2-yn-1-yl)-1H-1,5-benzodiazepin-2(3H)-one
  • N(3)-propargylated 2′-deoxyuridine, which can be encorporated in the DNA
  • chiral oxygenated acyclic natural products, via distereoselective propargylation of α-hydroxy aldehydes
