trans-1,4-dibromo-2-butene

Description:

Trans-1,4-dibromo-2-butene is an organic compound characterized by its structure, which features a butene backbone with two bromine substituents located at the 1 and 4 positions, and a trans configuration across the double bond. This compound is a member of the dibromoalkene family and is typically a colorless to pale yellow liquid at room temperature. It is known for its reactivity due to the presence of the double bond and the bromine atoms, which can participate in various chemical reactions, including electrophilic addition and substitution reactions. The trans configuration imparts specific geometric properties that influence its physical and chemical behavior, such as boiling and melting points, as well as its solubility in organic solvents. Trans-1,4-dibromo-2-butene is used in organic synthesis and may serve as an intermediate in the production of other chemical compounds. Safety precautions should be observed when handling this substance, as it may pose health risks due to its bromine content and potential reactivity.
