2-chloro-4-ethynylpyridine

Description:
2-Chloro-4-ethynylpyridine is an organic compound characterized by its pyridine ring, which is a six-membered aromatic heterocycle containing one nitrogen atom. The presence of a chloro group at the second position and an ethynyl group at the fourth position of the pyridine ring contributes to its unique chemical properties. This compound is typically a colorless to pale yellow liquid or solid, depending on its state at room temperature. It is known for its reactivity, particularly in nucleophilic substitution reactions due to the electron-withdrawing nature of the chloro substituent. The ethynyl group introduces a triple bond, which can participate in various coupling reactions, making it useful in synthetic organic chemistry. Additionally, 2-chloro-4-ethynylpyridine may exhibit biological activity, which can be explored in medicinal chemistry. Its solubility in organic solvents and relatively low solubility in water are typical for such compounds, influencing its applications in various chemical processes and research. Safety precautions should be taken when handling this substance, as it may pose health risks.
