| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| Introduction | 3-fluorophenylacetylene is a hydrocarbon derivative and is a terminal alkyne. The addition reaction of terminal alkyne is widely used in the synthesis of drugs, pesticides and organic functional materials. The reason why this kind of reaction is important is that there is an alkyne bond in the product, which can be further functionalized, so it is an important class of organic synthesis intermediates. |
| Uses | 3-fluorophenylacetylene can be used as an intermediate in pharmaceutical synthesis and is a terminal acetylene. |
