1-Bromo-3-ethynylbenzene

Description:

1-Bromo-3-ethynylbenzene, with the CAS number 766-81-4, is an organic compound characterized by the presence of a bromine atom and an ethynyl group attached to a benzene ring. This compound features a triple bond between the carbon atoms of the ethynyl group, which contributes to its reactivity and potential applications in organic synthesis. It is typically a colorless to pale yellow liquid or solid, depending on its purity and form. The presence of the bromine atom makes it a useful intermediate in various chemical reactions, including nucleophilic substitutions and coupling reactions. Additionally, the ethynyl group enhances its utility in the synthesis of more complex organic molecules, particularly in the field of materials science and pharmaceuticals. 1-Bromo-3-ethynylbenzene is generally handled with care due to its potential toxicity and reactivity, and it should be stored in a cool, dry place away from incompatible substances.
