1-Bromo-2-pentyne acts as a reagent for organic and organometallic compounds. It is also employed in the preparation of stereochemically restricted lactone-type analogs of jasmonic acids, 5-oxa-7-epi-jasmonic acid and 5-oxa-jasmonic acid. Further, it is used to prepare of 4,7-decadienal, 4,7-tridecadienal, 5,8-tetradecadienal and 6,9-dodecadienal synthesis. In addition to this, it plays an important role for the synthesis of 5-ethyl-4-methylene-6-phenyl-3a,4,7,7a-tetrahydroisobenzofuran-1,3-dione.
