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

During the 1960s, propargyl bromide (3-bromopropyne, C(3)H(3)Br, or 3BP) was used in a soil fumigant Trizone, a combination of chloropicrin, methyl bromide, and propargyl bromide. Since a great deal of attention is being placed on finding replacements for methyl bromide
