Product Description:
1 - BROMO - 2 - BUTYNE usually presents as a colorless to pale - yellow liquid. Structurally, it is an alkyne compound with a straight - chain structure containing four carbon atoms. There is a triple bond between the second and third carbon atoms, which endows the molecule with high reactivity typical of alkynes. At the first carbon atom, a bromine atom is attached. The bromine atom, being electronegative, makes the adjacent carbon atom electrophilic, prone to nucleophilic substitution reactions. The presence of the triple bond not only influences the compound's chemical reactivity but also affects its physical properties, such as its relatively high boiling point compared to similar - sized non - alkyne compounds due to the increased intermolecular forces associated with the unsaturated carbon - carbon bond.

In terms of solubility, it has low solubility in water because of its non - polar hydrocarbon backbone. However, it is highly soluble in common organic solvents like diethyl ether, hexane, and chloroform. Under normal storage conditions, it is relatively stable. But it can react vigorously with strong bases or nucleophiles. For example, when reacting with a strong base, an elimination reaction may occur, resulting in the formation of a more stable alkyne or an allene derivative. Exposure to heat or light can also trigger decomposition or unwanted side reactions.

In the field of organic synthesis, 1 - BROMO - 2 - BUTYNE is a valuable building block. It can be used to synthesize a variety of functionalized alkynes through reactions with different nucleophiles. For instance, reacting it with an organometallic reagent can lead to the formation of a new carbon - carbon bond, enabling the construction of more complex organic molecules. In the pharmaceutical and materials science industries, it may serve as an intermediate for the synthesis of compounds with specific biological activities or unique material properties. To maintain its quality and prevent unwanted reactions, it should be stored in a cool, dark place, away from moisture, strong bases, and oxidizing agents.

Application: 

It is mainly used as an intermediate of lilalitine.
