:1-Bromo-2-butyne
Description:
1-Bromo-2-butyne is an organic compound characterized by its alkyne functional group, specifically a terminal alkyne due to the presence of a triple bond between the second and third carbon atoms in the butyne chain. Its molecular formula is C4H7Br, indicating it contains four carbon atoms, seven hydrogen atoms, and one bromine atom. The compound is typically a colorless to pale yellow liquid with a distinctive odor. It is known for its reactivity, particularly in nucleophilic substitution reactions due to the presence of the bromine atom, which can be replaced by various nucleophiles. 1-Bromo-2-butyne is also used as an intermediate in organic synthesis, particularly in the preparation of more complex molecules. It is important to handle this compound with care, as it may be harmful if inhaled or absorbed through the skin, and appropriate safety measures should be taken during its use. Additionally, it is insoluble in water but soluble in organic solvents, which is typical for many halogenated hydrocarbons.
